Patent ID: 7132209

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 , and R 4 are, independently, H, an alkyl group, an alkaryl group, or an aryl group; X 1 and X 2 are, independently, a linking group having the formula —(CH 2 ) m —, branched or linear, where m is an integer between 1 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, a NR 5 group, a CHR 6 group, or a CR 7 R 8 group where R 4 , R 5 , R 6 , and R 7 are, independently, H, hydroxyl group, thiol group, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group; and Y 1 , Y 2 , and Y 3 are, independently, an arylamine group; and (b) a charge generating compound.
