Patent ID: 7037632

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 n is an integer between 2 and 6, inclusive; R 1 and R 2 are, independently, H, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group; R 3 and R 4 are, independently, H, halogen, carboxyl, hydroxyl, thiol, cyano, nitro, aldehyde group, ketone group, an ether group, an ester group, a carbonyl group, an alkyl group, an alkaryl group, or an aryl group; X is a linking group having the formula —(CH 2 ) m —, branched or linear, where m is an integer between 0 and 20, inclusive, and one or more of the methylene groups can be 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 5 , R 6 , R 7 , and R 8 are, independently, H, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group; and Y comprises a bond, C, N, O, S, a branched or linear —(CH 2 ) p —group where p is an integer between 0 and 10, an aromatic group, a cycloalkyl group, a heterocyclic group, or a NR 9 group where R 9 is hydrogen atom, an alkyl group, or aryl group, wherein Y has a structure selected to form n bonds with the corresponding X groups; and (b) a charge generating compound.
