Patent ID: 7326506

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 Z 1 and Z 2 comprise, each independently, a bond, a vinyl group, or a —CR 3 ═N—N═CR 4 — group; Y 1 and Y 2 comprise, each independently, an aromatic group; X 1 and X 2 are, each independently, a linking group; W 1 and W 2 are, each independently, a —(CH 2 ) n — group or a —(CH 2 ) n-1 —C(═O)— group, where n is an integer between 1 and 10, inclusive; Q 1 and Q 2 are, each independently, O, S, or NR; and R 1 , R 2 , R 3 , R 4 , R, R′, and R″ comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an acyl group, a heterocyclic group, or an aromatic group; and (b) a charge generating compound.
