The present invention is directed to a silicon-containing triarylamine compound represented by the formula (1): ##STR1## wherein Q.sub.2 and Q.sub.3 independently represent a hydrogen atom or --CH.sub.2 SiR.sub.1 R.sub.2 R.sub.3 group (R.sub.1, R.sub.2 and R.sub.3, which may be identical or not, independently represent an alkyl group, cycloalkyl group, aralkyl group or aryl group which may be substituted); Ar.sub.1, Ar.sub.2 and Ar.sub.3 independently represent an arylene group which may be substituted; Q.sub.1 represents a --CH.sub.2 SiR.sub.1 R.sub.2 R.sub.3 group, --CH.sub.2 SiR.sub.1 R.sub.2 R.sub.4 group (R.sub.4 represents the following: ##STR2## wherein Q.sub.2 and Q.sub.3 independently represent a hydrogen atom) or --CH.sub.2 SiR.sub.1 R.sub.4 R.sub.4 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.
本发明涉及一种由以下式(1)表示的含硅三芳胺化合物:其中Q.sub.2和Q.sub.3分别代表氢原子或--CH.sub.2 SiR.sub.1 R.sub.2 R.sub.3基团(R.sub.1,R.sub.2和R.sub.3,可以相同也可以不同,分别代表可以被取代的烷基,环烷基,芳基或取代的芳基);Ar.sub.1,Ar.sub.2和Ar.sub.3分别代表可以被取代的芳基;Q.sub.1代表--CH.sub.2 SiR.sub.1 R.sub.2 R.sub.3基团,--CH.sub.2 SiR.sub.1 R.sub.2 R.sub.4基团(R.sub.4代表以下基团:其中Q.sub.2和Q.sub.3分别代表氢原子)或--CH.sub.2 SiR.sub.1 R.sub.4 R.sub.4基团,以及其生产方法和作为电子照相的感光鼓,其包含作为电荷传输材料的化合物。这种感光鼓在灵敏度和耐久性方面非常出色。
