PHOTOINDUCED CHARGE-TRANSFER IN POLY(METHYL-PHENYLSILYLENE)

Photoconductivity in rigid polymers is based on complex processes incl uding photoinduced electron transfer, formation of ion pairs and their dissociation in an external electric field. Thus, the charge carrier photogeneration in macromolecules differs largely from the direct band -gap excitation and the formation of free electrons and holes in inorg anic materials. The processes mentioned above were studied on a catena silicon polymer, namely poly (methyl-phenylsilylene).
