Patent ID: 6864025

Claim:
An organophotoreceptor comprising: (a) a charge transport composition comprising molecules having the formula where the average n is between 1 and 1000; R 1 , R 2 , R 3 , and R 4 are, independently, hydrogen, a branched or linear alkyl group, a branched or linear unsaturated hydrocarbon group, an ether group, a cycloalkyl group, or an aryl group; X is a divalent carbazole group or a divalent biscarbazole alkane group; Y is a divalent sulfonyldiphenylene group; Z is C(R 4 )—X—C(R 3 )═O double-bonded to the adjacent N or two hydrogens where each hydrogen is independently single-bonded to the adjacent N; and Q is O or N—N(R 1 )—Y—N(R 2 )—NH 2 ; (b) a charge generating compound; and (c) an electrically conductive substrate over which the charge transport composition and the charge generating compound are located.
