摘要：

The photogeneration of charge carriers in thin films of poly(methylphenylsilylene) (PMPSi) and its derivatives with attached pendant pi-conjugated chromophores was investigated as a function of the electric field and temperature by the photoinduced discharge current method. Six new substituted polysilylenes were used in this study. The electric field dependence of photogeneration efficiency suggests that the Onsager theory of geminate recombination is a suitable model for the description of the electron-hole pair dissociation during the photogeneration process in these polymers. The most effective separation distances of electron-hole pairs participating in the photogeneration process were found to be 1.8-3.5 nm and 0.9-1.75 nm for low and high electric fields, respectively.
