摘要:
New type of surface modification of redox-couple multilayers on nanoporous TiO2film has been demonstrated. N,N′-bis(ethylphosphonic acid)-4,4′-bipyridinium chloride(VP) and N,N′-bis(ethyl dihydrogen phosphate)-3,4,9,10-perylene bis(dicarboximide)(EPPI) were directly coordinated at surface defect site Ti4+of nanoporous TiO2film electrode. The sequential adsorption by alternating treatment of ZrOCl2and VP or EPPI allows building up zirconium phosphonate multilayers of the redox couples. Cyclic voltammetry and UV-visible absorption measurement have shown the systematic layer-by-layer growing of the multilayers and the heterogeneous electron-transfer from TiO2conduction band to the redox couples multilayers. The estimated average amount of the redox couples in each layer on the electrode was about 1.0 × 10−11mole/cm2which is in agreement with the reported density of states assigned to surface Ti4+sites.

摘要:
Vacuum deposited gold thin layer on a ultraviolet (UV) light pre-exposed polysilanc film undergoes colloidal gold formation by heating. This process was found to accompany the degradation of polysilane by catalytic oxidation due to the colloidal gold formed. Incorporating a titanyl phthalocyanine (TiOPc) pigment layer as a photon-thermal energy conversion layer in-between polysilane film and substrate, we have succeeded in demonstrating experimentally the possible application of such phenomenon to a new optical recording system.

摘要:
Korea-Japan Joint Forum (KJF), an annual bilateral joint forum, has been successively organized since 1990. The objectives of KJF are to promote our research activities through sharing the most recent information, discussion of mutual interests between two countries on the field of advanced organic materials.
