Patent ID: 7432028

Claim:
An organophotoreceptor comprising: (a) a charge transport composition comprising molecules having the formula where n is an average of a distribution of integers in which n is at least 2; R 1 , R 2 , R 3 , and R 4 comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; X comprises an (N,N-disubstituted)arylamine group; and Y is a bridging group, wherein Y comprises a —(CH 2 ) m — group where 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, Si, B, P, C═O, O═S═O, a heterocyclic group, an aromatic group, urethane, urea, an ester group, an NR 5 group, a CR 6 , or a CR 7 R 8 group where R 5 , R 6 , R 7 , and R 8 are, each independently, a bond, H, hydroxyl, thiol, carboxyl, an amino group, an alkyl group, an alkenyl group, a heterocyclic group, an aromatic group, or part of a ring group and wherein if the bridging group contains a sulfur atom then the bridging group must contain at least two sulfur atoms; (b) a charge generating compound; and (c) an electrically conductive substrate over which the charge transport composition and the charge generating compound are located.
