Photoconductivity of C 60 ‐doping benzocarbazole‐substituted polysiloxanes on an operating wavelength of 633 nm

A novel polysiloxane having benzo[ a ]carbazole, benzo[ a,i ]carbazole, and benzo[ a,g ]carbazole pendant groups has been synthesized and characterized. We studied the electric‐field‐induced xerographic properties, the photogeneration efficiency, and the photoconductivity of C 60 ‐doping polymeric composites at a wavelength of 633 nm. C 60 ‐doping with benzo[ a,g ]carbazole‐substituted polysiloxane shows a photogeneration efficiency of 56.55 × 10 −5 and a photoconductivity of 52.2 pS/cm at E  = 100 V/µm, which was found to be higher than that of the other benzocarbazole‐substituted polysiloxane composites.
