The present invention is directed to a silicon-containing triarylamine compound represented by the formula (1):
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:
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.
本发明涉及一种由式(1)表示的含硅三芳基胺化合物:
其中 Q₂ 和 Q₃ 独立地代表氢原子或-CH₂SiR₁R₂R₃基团(R₁、R₂ 和 R₃ 可以相同或不相同,独立地代表烷基、环烷基、芳烷基或芳基,可被取代);Ar₁、Ar₂ 和 Ar₃ 独立地代表可被取代的芳烯基;Q₁ 代表 -CH₂SiR₁R₂R₃ 基团、-CH₂SiR₁R₂R₄ 基团(R₄ 代表以下基团:
其中 Q₂ 和 Q₃ 各自代表一个氢原子)或-CH₂SiR₁R₄R₄ 基团、其生产方法以及将其作为电荷传输材料的电致发光用感光元件。这种光感受器在灵敏度和耐用性方面都非常出色。
