Quantum gains of photophysical processes in media based on organic molecular charge-transfer complexes

摘要

For main classes of molecular charge-transfer (CT)-complexes used for xerographic media, the regularities of the changing of the gains of photoprocesses are estimated. It is shown that for homological arrays of CT complex molecules having a constant CT distance, a parameters of photoprocesses (such as a optical CT degree, dipole moment, quantum gains of thermalized coulomb connected pairs and of free charge carrier photogeneration) are connected uniquely with a energy and space parameters. Established regularities allow to predict a unknown values of gains for known-structure CT complex molecules and to estimate a limit value of photoprocesses gains and photosensitivity of media based on CT complexes and photoprocesses mentioned above.
