An organophotoreceptor that includes: (a) a charge transport compound having the formula where n is an integer between 2 and 6, inclusive; R1 is an aryl group (e.g., a phenyl or naphthyl group); R2 is a sulfolanyl group a pyrrolyl group; a tetrazolyl group; a benzotriazolyl group; a 4-(9H-fluoren-9-ylidene)benzyl group; a stilbenyl group; an alkylsulfonylphenyl group, an arylsulfonylphenyl; and a pyrazolyl group, with the proviso that when R2 is an alkylsulfonylphenyl group or an arylsulfonylphenyl, R1 may be hydrogen, an alkyl group, or an aryl group; X is an alkylene linking group having the formula -(CH2)m-, branched or linear, where m is an integer between 0 and 20, inclusive, and one or more methylene groups in the alkylene group is optionally replaced by an oxygen atom, a carbonyl group, urethane, urea, an ester group, a -NR3 group, a CHR4 group, or a CR5R6 group where R3, R4, R5, and R6 are, independently, H, an alkyl group, or aryl group; and Y is a bond, carbon atom, nitrogen atom, oxygen atom, sulfur atom, a branched or linear -(CH2)p- group where p is an integer between 0 and 10, an aryl group, a cycloalkyl group, a cyclosiloxyl group (e.g., a cyclotetrasiloxyl group), a heterocyclic group, or a CR7 group where R7 is hydrogen atom, an alkyl group, or aryl group; (b) a charge generating compound; and (c) an electrically conductive substrate.
