摘要：

A new photoconducting polymer with extended cooperative electronics effects, poly((E,E)-[6.2]paracyclophane-1,5-diene) (PDE), doped with a low molecular weight organic acceptor, 2,4,7-trinitrofluorenone (TNF), was investigated by means of steady-state photoconductivity and xerographic discharge methods. The photogeneration quantum yield in the PDE+TNF charge transfer (CT) complex for blue light is comparable with the photogeneration yield in poly(N-vinylcarbazole) (PVK) doped with TNF. It is demonstrated that the electric-field dependence of the photogeneration quantum yield in PDE+TNF systems can be described by the Braun kinetic model of dissociation of the CT complex, and not by the Onsager model of geminate recombination, which is appropriate for PVK+TNF systems.
