Abstract
Organophotoreceptors comprise an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising:a) a charge transport compound having the formula where R1 and R2 are, independently, hydrogen, an alkyl group, a heterocyclic group, an alkaryl group or an aryl group; X is an aromatic group; Y is an (N,N-disubstituted) arylamine group, such as a (N,N-disubstituted) arylamine group, a carbazole group or a julolidine group; Z is (CH2)m group where m is an integer between 1 and 30 where one or more of the methylene groups is optionally replaced by O, S, C═O, O═C—O, O═C—NR3, sulfoxide, sulfate, phosphate, an aryl group, urethane, urea, a NR4 group, a CHR5 group, or a CR6R7 group where R3, R4, R5, R6, and R7 are, independently, H, hydroxyl, thiol, an amine group, an alkyl group, a heterocyclic group, an alkaryl group, or an aryl group; and E is an epoxy group; and(b) a charge generating compound.
