Organophotoreceptors comprise an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: n a) a charge transport compound having the formula n where R 1 and R 2 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 (CH 2 ) 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—NR 3 , sulfoxide, sulfate, phosphate, an aryl group, urethane, urea, a NR 4 group, a CHR 5 group, or a CR 6 R 7 group where R 3 , R 4 , R 5 , R 6 , and R 7 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 n (b) a charge generating compound. |
