Photoelectric properties of a system of polymer with conjugated bonds and electron acceptor compound

1. The presence of a photoeffect in polymers with a system of conjugation was demonstrated in an electrophotographic system, but the value of the photosensitivity is small. 2. The introduction of low-molecular electron acceptor compounds into polymers with a system of conjugation leads to an appreciable increase in the electrophotographic sensitivity. 3. For the donor polymer-acceptor polymer system, an increased photosensitivity is observed, with a simultaneous conservation of film-forming properties and thermal stability. 4. The mechanism of the chemical sensitization of the photoconductivity was studied in a heterophase system of conjugated polymer-electron acceptor compound. In such a system the process consists of sensitization of the organic semiconductor by electron acceptor compounds, adsorbed on its surface with polymer molecules.
