Novel organic silicon compound, method of its production, and photoreceptor for electrophotography incorporating it.

摘要

The present invention is directed to a silicon-containing triarylamine compound represented by the formula (1): <CHEM> wherein Q2 and Q3 independently represent a hydrogen atom or -CH2SiR1R2R3 group (R1, R2 and R3, which may be identical or not, independently represent an alkyl group, cycloalkyl group, aralkyl group or aryl group which may be substituted); Ar1, Ar2 and Ar3 independently represent an arylene group which may be substituted; Q1 represents a -CH2SiR1R2R3 group, -CH2SiR1R2R4 group (R4 represents the following: <CHEM> wherein Q2 and Q3 independently represent a hydrogen atom) or -CH2SiR1R4R4 group, a method of its production and a photoreceptor for electrophotography incorporating it as a charge transport material. The photoreceptor is very excellent in sensitivity and durability.
