Abstract:
An organic photoreceptor comprising:(a) a charge transport compound having the formula â€ƒwhere R1 and R2, independently, are hydrogen, an alkyl group, or an aryl group; R3 is hydrogen or a hydrazone group having the formula R4 and R5, independently, are hydrogen, an alkyl group, or an aryl group; R6 is an aryl group; straight or branched alkyl group having at least 7 carbon atoms; a group having the formula â€”(CH2)nâ€”Ar where n is at least 3, Ar represents an unsubstituted aryl group, and one or more methylene groups is optionally substituted with a heteroatom; or a carbazole group having the formula where R7, R8, R9, and R10, independently, are hydrogen, an alkyl group, or an aryl group; n is at least 3; and one or more methylene groups is optionally substituted with a heteroatom, with the proviso that when R3 is hydrogen, R6 is not an aryl group; (b) a charge generating compound; and (c) an electroconductive substrate.
