Patent ID: 6964833

Claim:
An organophotoreceptor comprising: (a) a charge transport compound having the formula where n is an integer from 0 to 1; X is an (N,N-disubstituted)arylamine group; Ar is an aryl group or a heterocyclic group; A is a first linking group with the formula —(CH 2 ) p — which can be branched or linear, where p is an integer from 3 to 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; and B is a second linking group having the formula -Q-Z-Q′-, where Q and Q′ are, independently, O, S, or NR 1 ; wherein when Q or Q′ is NR 1 or Q=O and Q′=S, Z comprises an aryl group, and wherein when Q=Q′=S or Q=Q′=O, Z comprises a multi-ring conjugated group or —Y—W—Y′— wherein Y and Y′ comprise, independently, an aryl group and W comprises a CR 2 R 3 group; wherein R 1 is hydrogen or comprises an alkyl group or an aryl group; R 2 is a hydrogen or comprises an alkyl group, or an aryl group; and R 3 comprises an alkyl group or an aryl group or may form a ring structure along with the R 2 group; (b) a charge generating compound; and (c) an electrically conductive substrate over which the charge transport compound and the charge generating compound are located.
