Patent ID: 7179574

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 R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 , are, each independently, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heterocyclic group; R 9 and R 10 are, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heterocyclic group; Ar 1 and Ar 2 are, each independently, an aromatic group; Y comprises an arylamine group; and X 1 and X 2 comprise, each independently, a —(CH 2 ) m —N(R 11 )—N═C(R 12 )— group, where R 11 and R 12 are, each independently, hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heterocyclic group, m is an integer between 1 and 30, inclusive, and one or more of the methylene groups is optionally replaced by O, S, N, C, B, Si, P, C═O, O═S═O, a heterocyclic group, an aromatic group, an NR a group, a CR b group, a CR c R d group, or a SiR c R f where R a , R b , R c , R d, R e , and R f are, each independently, H, a hydroxyl group, a thiol group, a carboxyl group, an amino group, an alkyl group, an alkoxy group, an alkenyl group, an alkynyl group, a heterocyclic group, an aromatic group, or a part of a ring group; and (b) a charge generating compound.
