PHOTO-INDUCED CHARGE TRANSFER IN POLY(METHYL-PHENYLSILYLENE)

Photoconductivity in rigid polymers is based on complex processes including photo-induced 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 inorganic materials. The processes mentioned above were studied on a catena silicon polymer, namely poly(methyl-phenylsilylene).
