摘要:
Improved organophotoreceptors comprise: (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 —(CH2)p — which can be branched or linear, where p is an integer from 3 to 20 inclusive; and B is a second linking group having the formula -Q-Z-Q′, where Q and Q′ are, independently, O, S, or NR1; wherein when Q or Q′ is NR1 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; (b) a charge generating compound; and (c) an electrically conductive substrate over which said charge transport compound and said charge generating compound are located.
