    摘要： An organophotoreceptor that includes (a) a charge transport compound having the formula
       where n is an integer between 2 and 6, inclusive; R 1 is an aryl group (e.g., a phenyl or naphthyl group); R 2 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; or a pyrazolyl group, with the proviso that when R 2 is an alkylsulfonylphenyl group or an arylsulfonylphenyl, R 1 may be hydrogen, an alkyl group, or an aryl group; X is a linking alkylene group having the formula -(CH 2 ) 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 -NR 3 group, a CHR 4 group, or a CR 5 R 6 group where R 3 , R 4 , R 5 , and R 6 are, independently, H, an alkyl group, or aryl group; and Y is a chemical bond, carbon atom, nitrogen atom, oxygen atom, sulfur atom, a branched or linear -(CH 2 ) 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 CR 7 group where R 7 is hydrogen atom, an alkyl group, or aryl group; (b) a charge generating compound; and (c) an electrically conductive substrate.
