Patent ID: 7300732

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 following formula: where R comprises a hydrogen, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; X comprises an arylamine group selected from the group consisting of a carbazole group, a julolidine group and a p-N,N-diphenylaminophenylene moiety; and Y comprises a 9-fluorenylidene group having at least a solubilizing substituent, wherein the solubilizing substituent comprises a —(CH 2 ) n H group where n is an integer between 1 and 50, 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, a CR c R d group, or a SiR e R f where R c , R d , R e ,and R f are, each independently, H, a hydroxyl group, a thiol group, a carboxyl group, an amino group, an alkyl group, an alkoxy group, an alkenyl group, a heterocyclic group, or an aromatic group, or part of a ring group, and wherein the solubilizing substituent is not an alkyl moiety or an alkoxy moiety; and (b) a charge generating compound.
