Electron-transport liquid crystalline polymeric compounds, electrophotographic elements comprising same, and electrophotographic process

摘要

Disclosed are electron-transport polymeric liquid crystalline compounds having the formula (I) <IMAGE> (I) wherein A and B are alkylsubstituted siloxane or acrylate repeating units; S1 and S2 are alkylene spacer groups; L is a mesogenic group; ET is an electron-transport functionality; and x and y are integers, the ratio of x to y is from about 100 to about 0.1, the sum of x and y is from about 5 to about 100. Multi-active and single active electrophotographic elements comprising these compounds and electrophotographic processes are also disclosed.
