Abstract
Organic electron donor compounds for use in electrophotographic constructions tend to suffer from problems of molecular weight non-uniformity and oxidation. Bis-benzocarbazole derivatives have been found to resist the oxidation and oligomerization which are a source of these problems.
Claims14
An electronically active photoconductive insulating layer comprising a polymeric binder and an electrically active donor compound of the formula ##STR8## where X is a group selected from ##STR9## wherein R and Y are independently selected from the group consisting of aliphatic, aromatic, heterocyclic, and mixed aliphatic-aromatic groups.
