Patent ID: 7261987

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 comprises an aromatic group; X is a —(CH 2 ) n — group, where n is an integer between 1 and 10, inclusive, and one or more of the methylene groups is optionally replaced by O, S, C═O, O═S═O, an NR a group, or a CR c R d group, where R a , R c , and R d , are, each independently, H, a hydroxyl group, a thiol group, a carboxyl group, an amino group, a halogen, an alkyl group, an acyl group, or an alkoxy group; Q 1 , Q 2 , and Q 3 are, each independently, O, S, or NR; R 1 comprises H, an alkyl group, an alkenyl group, an alkynyl group, an amino group, an acyl group, an alkoxy group, an aromatic group, or a heterocyclic group; R and R 2 comprise, each independently, H, an alkyl group, or an alkoxy group; and R 3 comprises a bond linking Y and the carbon atom adjacent to Y, H, an alkyl group, or an alkoxy group; and (b) a charge generating compound.
