ABSTRACT:
Disclosed is a photoreceptor comprising at least one substantially non-charge-injecting contact in a charge-collecting relationship with a solid phase consisting essentially of a compound having the general formula ##STR1## where each R is independently selected from hydrogen, alkyl from C.sub.1 to C.sub.8, aryl from C.sub.6 to C.sub.14, one or more fused benzene rings formed by adjacent R groups, halogen, cyano, and alkoxy from C.sub.1 to C.sub.8, each X is independently selected from S and O, and R.sub.1 is a conjugated bridging group. Also disclosed is a method of making that photoreceptor.
