Patent ID: 7261988

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 X comprises an —Ar 1 —OCH 2 CH(Q 3 H)CH 2 —Q 1 —Z 1 —Q 2 —CH 2 CH(Q 4 H)CH 2 O—Ar 2 — group where Q 1 , Q 2 , Q 3 and Q 4 are, each independently, O, S, or NR where R is H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; Z 1 comprises an aromatic group or a heterocyclic group; and Ar 1 and Ar 2 are, each independently, an aromatic group, wherein Ar 1 and Ar 2 are, each independently, a C 6 R 4 R 5 R 6 R 7 group, where R 4 , R 5 , R 6 and R 7 are, each independently, H, a halogen, a nitro group, a cyano group, a hydroxyl group, a thiol group, a carboxyl group, an alkyl group, an alkoxy group, an alkenyl group, an alkynyl group, a heterocyclic group, an aromatic group, or part of a ring group; R 1 and R 1 ′ comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a hetero cyclic group; and R 2 , R 3 , R 2 ′, and R 3 ′ comprise, each independently, an arylamine group; and (b) a charge generating compound.
