This invention relates to a novel organophotoreceptor that includes:n (a) a charge transport compound having the formula n n where n is an integer from 0 to 1 inclusive;n X is an (N,N-disubstituted)arylamine, such as a carbazole group, a julolidine group, or a p-(N,N-disubstituted)arylamine group (which can be a triarylamine, an alkyldiarylamine or a dialkylarylamine); n Ar is an aryl group or a heterocyclic group; A is a linking group having the formula —S—(CH 2 ) m —S— where m is an integer from 1 to 15 inclusive and; B is a second linking group with the formula —(CH 2 ) p — which can be branched or linear, where p is an integer from 3 and 20 inclusive and where one or more methylene groups can be optionally replaced by O, S, a carbonyl group, urethane, urea, an ester group, a —NR 21 group, a CHR 22 group, or a CR 23 R 24 group where R 21 , R 22 , R 23 and R 24 are, independently, H, hydroxyl, thiol, an amine group, an alkyl group, an alkaryl group, an aryl group, or part of a ring; (b) a charge generating compound; and (c) an electrically conductive substrate over which the charge transport compound and the charge generating compound are located. |
