Abstract:
1. 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 Y and Y′ comprise, each independently, a 9-fluorenylidene group and X is a conjugated linking group that allows the delocalization of pi electrons over at least Y and Y′, wherein X is selected from the group consisting of a 1,2-ethanediylidene group, a 1,4-phenylenedimethylidyne group, a 2,4-cyclohexadienylidene group, a 2,5-cyclohexadienylidene group, a bicyclohexylidene-2,5,2′,5′-tetraene group, a bicyclohexylidene-2,4,2′,4′-tetraene group, a combination thereof, and a (C (b) a charge generating compound.
