Patent ID: 7094510

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 X-Z-X′ where X and X′, each independently, have the formula where Y is O—CH 2 —CH 2 —O, S, or NR 8 and R 8 is H, an alkyl group, an alkenyl group, an aromatic group, or a heterocyclic group, and Z is a linking group having the formula —(CH 2 ) m —, branched or linear, where m is an integer between 1 and 30, inclusive, and one or more of the methylene groups may be replaced by O, S, C═O, Si═O, S(═O) 2 , P(═O) 2 , an aromatic group, a heterocyclic group, an aliphatic cyclic group, a Si(R 1 )(R 2 ) group, a BR 3 group, a NR 4 group, a CHR 5 group, or a CR 6 R 7 group where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , and R 7 are, each independently, H, halogen, hydroxyl, thiol, an alkoxy group, an alkyl group, an alkenyl group, an aromatic group, a heterocyclic group, or a part of a cyclic ring; and (b) a charge generating compound.
