Summary:Copolysilanes containing carbazolyl-siloxane (CzSi) side chains were prepared to study surface potential decay behavior of their composite films. Two methods, i. e., direct reaction of CzSi-containing dichorosilane and two-stage reaction including hydrosilylation of poly (allylphenylsilane-co-methylphenylsilane), were applied for the preparation. The yields, molecular weights, and Cz group contents of the copolysilanes thus obtained were found to significantly depend on the preparation method and siloxane chain length (disiloxane or octasiloxane chain). For the copolysilanes coated on a charge-generation (CG) layer, it was found by ATR-FT-IR and ESCA spectra that siloxane groups were accumulated both at the air-side uppermost surface and the interface between the CG layer and copolysilane layer. Accumulation of siloxane groups, particularly at the latter interface, was speculated to lead to the formation of insulation layers and the decrease of surface potential decay in comparison with poly (methylphenylsilane).
