Patent ID: 7014968

Claim:
An organophotoreceptor comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a charge transport material having the formula where Y 1 and Y 2 are, each independently, a bond, —CR 1 ═N—NR 2 —, or —CR 3 ═N—N═CR 4 — where R 1 , R 2 , R 3 , and R 4 comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; X 1 and X 2 are, each independently, a linking group having the formula —(CH 2 ) m —, branched or linear, where m is an integer between 0 and 20, inclusive, and one or more of the methylene groups is optionally replaced by O, S, C═O, O═S═O, a heterocyclic group, an aromatic group, urethane, urea, an ester group, an NR 5 group, a CHR 6 group, or a CR 7 R 8 group where R 5 , R 6 , R 7 , and R 8 comprise, each independently, H, hydroxyl group, thiol group, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; T 1 and T 2 are, each independently, a thiiranyl group, H, an alkyl group, an alkenyl group, or an aromatic group with the proviso that at least one of T 1 and T 2 is a thiiranyl group; and Ar comprises an aromatic group with the proviso that when both Y 1 and Y 2 are a bond and one of T 1 and T 2 is not a thiiranyl group, Ar comprises a bis[(N,N-disubstituted)amino]aromatic group or a bicarbazole group; and (b) a charge generating compound.
