摘要:

Hole transport in the glassy state of arylaldehyde and arylketone hydrazones, 4-diphenyl-aminobenzaldehyde diphenylhydrazone (DPH) and 4-diphenylaminoacetophenone diphenylhydrazone (M-DPH), has been studied. The values of the hole drift mobility in the glassy state of DPH and M-DPH are over one order of magnitude greater than those of 50 wt% molecularly dispersed systems in polycarbonate. The hole drift mobility of DPH is ca. twice as high as that of M-DPH. Temperature and electric-field dependencies of the hole drift mobilities in the glassy state are discussed.

摘要:

The decrease of the hole mobility in polycarbonate doped with 17% of a triphenylaminobenzene derivative at electric fields exceeding 1.0 × 106Vcm−1is rationalized in the framework of the Marcus theory. By analysis of the mobility data in the framework of the expression, derived by Marcus and relating the free energy of election transfer to the free activation energy of this process, the average hopping distance, the reorganisation energy and the barrierless electron transfer rate constant could be obtained. In this way physical acceptable values, amounting to 2.7nm, 0.33eV, 4.88 × 106s−1, were found for the respective parameters at room temperature.

摘要:

To accurately separate the composite thermally stimulated current curve into single curves, the original concept of the fundamental element is indispensable. To accurately establish the peak coordinate as the clear standard leads to utilizing substantial quantities.
