2,5-BIS DIPHENYLAMINOPHENYL -1,3,4-OXADIAZOLES

摘要

Charge-transporting compounds which form substantially colorless layers having a minimal residual charge and a good cleanability are disclosed. These compounds are of the general formula: wherein R1, R2, and R3, individually, represent a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms. Also disclosed is a photoconductive element containing a charge-generating compound and a charge-transporting compound of the general formula shown above which is homogeneously distributed in a binder. The charge-transporting compounds of the general formula are very soluble in various solvents and film-forming polymers providing for great maneuverability in processing the compounds into layers.
