However, work that has appeared in print in a short form such as a Materials Chemistry Communication or Chemical Communication is normally acceptable. But note that the Society strongly discourages the fragmentation of a substantial body of work into a number of short publications. Papers should be typewritten in double spacing on one side only of the paper. Four copies of text, illustrations (full colour copies for coloured figuredplates), tables and any other matter should be sent to: The Editor, Journal of Materials Chemistry, The Royal Society of Chemistry, Thomas Graham House, Science Park, Milton Road, Cambridge CB4 4WF, UK Feature Articles Feature Articles are published by invitation of the Materials Chemistry Editorial Board.Materials Chemistry Communications Materials Chemistry Communications contain novel scientific work in short form and of such importance that rapid publication is desirable. Authors should briefly indicate in a covering letter the reasons why they feel that publication of their work as a Communication is justified. The total length is rigorously restricted to two printed A4 pages. The manuscript will be returned for reduction if this length is exceeded. For a Communication consisting of text and ten references, with no figures, equations or tables, this corresponds to approximately 1,600 words plus an abstract of up to 40 words.Submission of a Materials Chemistry Communication can be made either to The Editor, Journal of Materials Chemistry, The Royal Society of Chemistry, Thomas Graham House, Science Park, Milton Road, Cambridge CB4 4WF, UK or via a member of the International Advisory Editorial Board. In the latter case, the top copy of the manuscript including any figures etc., together with the name of the person to whom the Communication is being submitted, should be sent simultaneously to The Editor at the Cambridge address. Authors may wish to contact the Board member to ensure that he is available to arrange review of the manuscript within reasonable time.Administration Receipt of a paper will be acknowledged, and the paper will be given a reference number which authors are asked to quote on all their subsequent correspondence. If no such acknowledgement has been received after a reasonable period of time authors should check with the Editorial Office as to whether the paper or the acknowledgement has gone astray. Editorial Policy. Every paper (except Communications) will be submitted to at least two referees, by whose advice the Materials Editorial Board will be guided as to its acceptability. Full details are given in Refereeing Procedure and Policy, J. Mater. Chem., 1994, Issue 1. Papers that are accepted must not be published elsewhere except by permission of the Royal Society of Chemistry.Submission of a manuscript will be regarded as an undertaking that the same material is not being considered for publication by another journal. Conditions governing acceptance are available from the Editorial Office. Copyright. The whole of the literary matter (including tables, figures, diagrams and photographs) in Journal of Materials Chemistry is subject to copyright and may not be reproduced without permission from The Royal Society of Chemistry and such other owner of the copyright as may be indicated. Reprints. Fifty reprints of each paper are supplied free of charge on request. Additional reprints can be purchased if ordered at the time of publication. Details are sent to authors with the proofs.Notes on the Preparation of Papers 1. Manuscripts must by typed in double-line spacing, single sided on A4 paper, with margins at top, bottom and left-hand side of at least 4 cm. 2. The first page should be set out as follows: (i)Name and address of the author to whom the proofs and correspondence should be sent. (ii) Title of the paper, with capitals for the first letter of each noun and adjective only. (iii) Authors’ names, including one forename for each author. (iv) The address where the work was carried out; if this is different from the current address of any author wishing to deal with correspondence a footnote indicating the present address of this author should be included. (v) Abstract, preceded and followed by a horizontal line, and typed in double-line spacing. 3.Suitable headings and sub-headings should be used in the main text as appropriate (except for Communications in which no headings are used). References should be numbered serially in the text by means of superscript arabic numerals. 4. Bibliographic references (not footnotes) should follow the main text and should have the following format: 1 R.M. Barrer and R.J.B. Craven, J. Chem. Soc., Faraday Trans. 1,1987, 83,779. 2 R.M. Barrer and R.J.B. Craven, in New Developments in Zeolite Science and Technology, ed. Y. Murakame, A. Iijima and J.W. Ward, Kodansha, Tokyo, 1986, p.521. Journal titles should be abbreviated according to the Chemical Abstracts Service Source Index (CASSI).5. Tables should be typed on separate sheets at the end of the manuscript. Crystallographic Papers Crystallographic work will be assessed mainly for its relevance to materials. Papers reporting only the results of crystal structure determination may be accepted for publication provided they are for materials with potentially interesting properties, Crystallographic work that forms parts of a wider study, including synthesis or property measurements, should not normally be submitted for publication separately from the results of that study. Papers containing new crystal data should normally make explicit mention of this in the title. The description of a crystallographic structure determination should be as brief as possible; in particular, it is not the policy of the journal to publish lengthy data tables.For publication as part of their papers authors should include: a table of final fractional atomic coordinates (but without anisotropic temperature factors); a table of key bond lengths and angles; and a conventional line drawing of the structure. Additional data (any calculated coordinates; full list of bond lengths and angles; thermal parameters; structure factors; least-square planes) should be submitted as supplementary material for use by the referees. Apart from the structure factors this material will be deposited at the Cambridge Crystallographic Data Centre, 12 Union Road, Cambridge CB2 1EZ (for molecules with ‘organic’ carbon) or the Fachinformationszentrum Karlsruhe, D-7514 Eggenstein- Diagrams should be accompanied by a separately typed set of captions.Extensive identifying lettering should be placed in the captions rather than on the figures. Original artwork should be supplied wherever possible. Colour photographs will be accepted subject to approval by the referees. Bulk information (such as primary kinetic data, computer programs and output, etc) which accompanies papers published in Journal of Materials Chemistry may be deposited, free of charge, with the Society’s Supplementary Publications Scheme, either at the request of the author and with the approval of the referees or on the recommendation of the referees with the approval of the author. Details are available from the Editorial Office.Nomenclature Current IUPAC nomenclature and symbolism should be used. Attention is drawn to the following publications in which the rules themselves and guidance on their use are given: Nomenclature of Inorganic Chemistry, Blackwell Scientific Publications, Oxford, 1990. Nomenclature of Organic Chemistry, Sections A,B,C,D,E,F and H, Pergamon Press, Oxford, 1979 edn. Biochemical Nomenclature and Related Documents, The Biochemical Society, London, 1978. Compendium of Chemical Technology: IUPAC Recommendations, Blackwell Scientific Publications, Oxford, 1987. Units and Symbols The recommendations of IUPAC should be followed. Their basis is the Systkme Internationale d’Unit6s (SI).A detailed treatment is given in the so-called Green Book: Quantities, Units and Symbols in Physical Chemistry, Blackwell Scientific Publications, Oxford, 1993 edn. Leopoldshafen 2 (otherwise). Any request to Cambridge or the Fachinformationszentrum Karlsruhe for deposited material should be accompanied by the full literature citation for the paper concerned. Full details regarding presentation of crystallographic work can be obtained from the Editorial Office. Powder Data Powder X-ray diffraction data may be published, preferably in tabular form, but should be restricted to studies of new materials; also, for cases where the materials are new but have similar powder data to other, well characterized, materials, such data will not usually be included in the journal.However, for the purposes of refereeing, a full data set in tabular form should be submitted as supplementary material, simultaneously with the paper; this material will subsequently be deposited with the Society’s Supplementary Publications Scheme (details available from the Editorial Office). Diagrams showing diffraction patterns of reaction products will not normally be included in the journal, unless they have some distinct feature of particular relevance to the discussion. JOURNALS OF THE ROYAL SOCIETY OF CHEMISTRY Refereeing Procedure and Policy (1994) 1.0 Contributions to Dalton, Perkin and Faraday Transactions, J. Mater. Chem., The Analyst, J. Anal. At. Spectrom. and J. Chem.Research 1.1 Introduction This document summarises the procedure used for assessing papers submitted to the four Transactions, J. Mater. Chem., The Analyst, J. Anal. At. Spectrom., and J. Chem. Research, and provides guidelines for referees engaged in this assessment. 1.2 Subject Matter Papers are submitted to the various journals according to subject matter. If it is felt that a paper would be published more appropriately in an RSC journal other than the one suggested by the author, the referee should inform the Editor. The topics covered by the various journals are as follows. Dalton Transactions (Inorganic Chemistry). All aspects of the chemistry of inorganic and organometallic compounds, including bioinorganic chemistry and solid-state inorganic chemistry; the applications of physicochemical techniques to the study of their structures, properties and reactions, including kinetics and mechanism; new or improved experimental techniques and syntheses.Faraday Transactions (Physical Chemistry and Chemical Physics). Gas-phase kinetics and dynamics; molecular beam kinetics and spectroscopy, photochemistry and photophysics; energy transfer and relaxation processes: laser-induced chemistry; spectroscopies of molecules, molecular and gas- phase complexes: quantum chemistry and molecular structure, statistical mechanics of gaseous molecules and complexes; spectroscopies, statistical mechanics and quantum theory of the condensed phase, computational chemistry and molecular dynamics; colloid and interface science, surface science, physisorption and chromatographic science, chemisorption and heterogeneous catalysis, zeolites and non-exchange phenomena; electrode processes, liquids and solutions; solid-state chemistry (microstructures and dynamics); reactions in condensed phases; physical chemistry of macromolecules and polymers; materials science; thermodynamics; biophysical chemistry and radiation chemistry.

The format of this journal (one- or two-page printed synopsis in Part S, plus microform version of authors’ full text typescript in Part M) makes it particularly suitable for papers containing lengthy experimental sections or extensive data tabulations. 1.3 Procedure Each manuscript is considered independently by two referees.The referees’ reports constitute recommendations to the appropriate Editorial Board, which is empowered to take final action on manuscripts submitted. The Editor, acting for the Editorial Board, is responsible for all administrative and executive actions, and is empowered to accept or reject papers. It is the Editor’s duty to see that, as far as possible, agreement is reached between authors and referees; although the referees may need to be consulted again concerning an author’s reply to comments, further refereeing will be avoided as far as possible. 1.3.1 Adjudication of disagreements. If there is a notable discrepancy between the reports of the two referees, or if the difference between authors and referees cannot be resolved readily, a third referee may be appointed as adjudicator. In extreme cases, differences may be reported to the appropriate Editorial Board for resolution.When a paper is recommended for rejection by referees, the Editor will inform the authors and return the top copy of the manuscript. Authors have the right to appeal to the Editorial Board if they regard a decision to reject as unfair. The Editor may refer to the Editorial Boards any papers which have been recommended for acceptance by the referees, but about which the Editor is doubtful. 1.3.2 Anonymity. The anonymity of referees is strictly preserved, and reports should be couched in terms which do not disclose the identity of the writer. A referee should never communicate directly with an author, unless and until such action has been sanctioned by the Society, through the Editor.1.3.3 Conjidentiality. A referee should treat a paper received for assessment as confidential material. Information acquired by a referee from such a paper is not available for citation until the paper is published. REFEREEING PROCEDURE AND POLICY (1 994) 1.4 Policy The primary criterion for acceptance of a contribution for publication is that it should advance scientific knowledge significantly. Papers that do not contain new experimental results may be considered for publication only if they either reinterpret or summarise known facts or results in a manner presenting an advance in chemical knowledge.Papers in interdisciplinary areas are acceptable if the chemical content is considered satisfactory. Papers reporting results regarded as routine or trivial are not acceptable in the absence of other, desirable attributes. Although short papers are acceptable, the Society strongly discourages the fragmentation of a substantial body of work into a number of short publications; such fragmentation is likely to be grounds for rejection. The length of an article should be commensurate with its scientific content; however, authors are allowed every latitude (consistent with reasonable brevity) in the form in which their work is presented. Figures and flow-charts can often save space as well as clarify complicated arguments, and should not be excised unless they are unhelpful or really extrava- gant.If a paper as a whole is judged suitable for the Journal, minor criticisms should not be unduly emphasised. It is the responsibility of the Editor to ensure the use of reasonably brief phraseology, and to assist the author to present his work in the most appropriate format. However, referees should not hesitate to recommend rejection of papers which appear incurably badly com-posed. It should be clearly understood that referees’ reports are made in confidence to the Editor, at whose discretion comments will be transmitted to the author. To assist the Editor, referees are requested to indicate which comments are designed only for consideration, as distinct from those which, in the referee’s view, require specific action or an adequate answer before the paper is accepted.Referees may ask for sight of supporting data not submitted for publication, or for sight of a previous paper which has been submitted but not yet published. Such requests must be made to the Editor, not directly to the author. 1.4.1 Authentication of new compounds. Referees are asked to assess, as a whole, the evidence in support of the homogeneity and structure of all new compounds. No hard and fast rules can be laid down to cover all types of compounds, but the Society’s policy is that evidence for the unequivocal identification of new compounds should wherever possible include good elemental analytical data; for example, an accurate mass measurement of a molecular ion does not provide evidence of purity of a compound and must be accompanied by independent evidence of homogeneity.Low-resolution mass spectrometry must be treated with even more reserve in the absence of firm evidence to distinguish between alternative molecular formulae. Where elemental analytical data are not available, appropriate evidence which is convincing to an expert in the field may be acceptable. Spectroscopic information necessary to the assignment of structure should normally be given. Just how complete this information should be must depend upon the circumstances; the structure of a compound obtained from an unusual reaction or isolated from a natural source needs much stronger supporting evidence than one derived by a standard reaction from a precursor of undisputed structure.Referees are reminded of the need to be exacting in their standards but at the same time flexible in their admission of evidence. It remains the Society’s policy to accept work only of high quality and to permit no lowering of standards. 1.5 Titles and Summaries Referees should comment on titles and summaries with the following points in mind. Titles of papers are used out of context by several organizations for current awareness purposes. To enable such systems to serve chemists adequately, titles must be written around a sufficient number of scientific words carefully chosen to cover the important aspects of the paper. Summaries should preferably be self-contained, so that they can be understood without reference to the main text.1.6 Speed of Refereeing The Editorial Boards are anxious to maintain and to reduce further if possible the publication times now being achieved. In this connection, referees should submit their reports with the minimum of delay, or return manuscripts immediately to the Editor if long delay seems inevitable. 1.7 Suggestions of Alternative Referees The Editor welcomes suggestions of alternative referees competent to deal with particular subject areas. Such suggestions are particularly helpful in cases where referees consider themselves ill-equipped (in terms of specialist knowledge) to deal with a specific paper, and in highly specialized or new areas of research where only a limited number of experts may be available. If, in such a case, the alternative and the original referee work in the same institution, the manuscript may be passed on directly after informing the Editor.1.8 Short Papers and Letters ‘Short Papers’ are published in J. Chem. Research. They are intended for the description of essentially complete pieces of work which can be described in two printed pages or less. They are NOT preliminary communications, nor in any way an alternative to Chemical Communications, for which there are additional criteria of novelty and urgency. The quality of material contained in a short paper should be the same as that in a full paper. Investigations arising out of some larger project but not prosecuted to the same degree are particularly appropriate for this format.A short paper should not normally exceed in length about 8 pages of typescript, including figures, tables, etc. It should comprise a one-sentence abstract and discussion, but adequate experimental details are required. As a consequence of its length, it appears in full in Part S with no microform version in Part M. ‘Letters’, published only in Dalton Transactions, are a medium for the expression of scientific opinions and views normally concerning material published in that journal; it is intended that contributions in this format should be published rapidly. The letters section is for scientific discussion, and is not intended to compete with media for the publication of more general matters such as Chemistry in Britain.Only rarely should a Letter exceed one printed column in length (about 1-2 pages of typescript). Where a letter is polemical in nature, and if it is accepted, a reply will be solicited from other parties implicated, for consideration for publication alongside the original letter. 1.9 Relationship with Communications Journals In cases where a preliminary report of the work described has appeared (for example in Chemical Communications), referees should alert the editor to any excessive and unnecessary repetition of material; this can arise in connection with communications journals in which the restrictions on length ... Vlll REFEREEING PROCEDURE AND POLICY (1994) and the reporting of experimental data are less severe than those of Chemical Communications.Furthermore, the acceptability of the full paper must be judged on the basis of the significance of the additional information provided, as well as on the criteria outlined in the foregoing sections. 2.0 Contributions to Chemical Communic-ations Chemical Communications is intended as a forum for preliminary accounts of original and significant work, in any area of chemistry that is likely to prove of wide general appeal or exceptional specialist interest. Such preliminary reports should be followed up in most cases by full papers in other journals, providing detailed accounts of the work. It is Society policy that only a fraction of research work warrants publication in Chemical Communications, and strict refereeing standards should be applied.The benefit to the reader from the rapid publication of a particular piece of work before it appears as a full paper must be balanced against the desirability of avoiding duplicate publication. The needs of the reader, not the author, must be considered, and priority in publication should not be allowed to determine acceptability. Acceptance should be recommended only if, in the opinion of the referee, the content of the paper is of such urgency that rapid publication will be advantageous to the progress of chemical research. The length of Communications is strictly limited; only in exceptional circumstances should it exceed one printed page (two-and-a-half to three A4 pages of typescript) and referees should be particularly critical of manuscripts longer than this.Communications do not contain extensive spectroscopic or other experimental data, but referees may ask for sight of such data before reaching a decision. The refereeing procedure for Communications is the same as that for full papers, except that rapidity of reporting is crucial in order to maintain rapid publication. 3.0 Communications submitted to Analytical Proceedings and J. Anal. At. Spectrom. Criteria for acceptance of communications submitted to Analytical Proceedings and J. Anal. At. Spectrom. are similar to those for contributions to Chemical Communications, except that they should be concerned specifically with analytical chemistry.A decision whether or not to publish rests with the Editor, who will obtain advice from at least one referee. 4.0 Communications submitted to Perkin, Dalton or Faraday Transactions or J. Mater. Chem. Criteria for acceptance of Communications submitted to Perkin, Dalton or Faraday Transactions or J. Mater. Chem. are similar to those for contributions to Chemical Communications, except that the work will be of more specialist interest. For Perkin and Dalton Communications inclusion of key experi- mental data is expected. Assessment is carried out by a small nucleus of referees, consisting largely of members of the appropriate Editorial Boards. 5.0 Contributions to Mendeleev Communic- ations Mendeleev Communications, published jointly by the Royal Society of Chemistry and the Russian Academy of Sciences, is a sister publication to Chemical Communications, containing preliminary reports of the same type, in any area of chemistry.The majority of contributions are from Russian authors. Assessment involves two stages of refereeing. Manuscripts submitted to the Moscow Editorial Office are refereed initially by a Russian scientist. If found acceptable they are then reviewed by Western scientists chosen by the Royal Society of Chemistry. Manuscripts submitted to the UK Editorial Office undergo this two-stage refereeing process in reverse. 6.0 X-Ray Crystallographic Work 6.1 All papers containing crystallographic determinations will be refereed by two referees, one a structural chemist.If the editor considers it advisable, the paper may also be sent to a specialist crystallographer for comment. Referees will not normally be expected to check values of structural parameters for publication (e.g. bond lengths and angles against atomic co- ordinates; this will be done after publication by the appropriate crystallographic data centre), but should still pay attention to the quality of the experimental crystallographic work. However their primary concern should be such new chemistry as is involved in the structure. 6.2 Papers will often contain the information in their titles that an X-ray structure determination has been carried out. However, this is not obligatory, especially if the X-ray determination forms only a minor part.Summaries should normally contain this information. 6.3 A structure referred to in a Communiciition will normally be fully refined. The Communication can then be considered to fulfil the archival function, and the structure determination may not require further detailed refereeing when presented as part of a full paper. In the full paper, the author’s purpose will then be served by a simple reference back to the original communication. However, if the crystallography is discussed again at any length in the full paper, the data should be re-presented to the referees in full, and re-published if considered necessary. 6.4 There may be other cases when an author wishes to publish a full paper in which the result of a crystal structure determination is discussed, but in which details or extensive discussion are considered unnecessary.The crystallographer may even be omitted as a co-author (for example when the determination is carried out by a commercial company). If the author is able to show the referees that this procedure is appropriate, it will be allowed provided that it does not lead to unnecessary fragmentation. However, the author must provide, as supplementary information, sufficient data relating to the crystal structure determination to allow a referee to make sure that the point made is correct, and co-ordinates rtc. will be deposited. The brief published description of the determination should be supplemented by appropriate reference to ‘unpub- lis hed work’. ix INSTRUCTIONS FOR AUTHORS (1994) APPENDIX IUPAC Publications on Nomenclature and Symbolism 1.O Compilations 1.1 Nomenclature of Organic Chemistry, a 550-page hardcover volume published in 1979, available from Pergamon, Oxford.Section A: Hydrocarbons Section B: Fundamental heterocyclic systems Section C: Characteristic groups containing carbon, hy- drogen, oxygen, nitrogen, halogen, sulfur, selenium and tellurium Section D: Organic compounds containing elements not exclusively those referred to in the title of Section C Section E: Stereochemistry Section F: General principles for the naming of natural products and related compounds Section H: Isotopically modified compounds 1.2 A Guide to IUPAC Nomenclature of Organic Compounds, a 182-page hardcover volume published in 1993, available from Blackwell Scientific Publications, Oxford, to be used in conjunction with item 1.1.1.3 Nomenclature of Inorganic Chemistry, a 278-page hardcover volume published in 1990, available from Blackwell Scientific Publications, Oxford.
