Patent ID: 6864028

Claim:
An organophotoreceptor comprising: (a) a charge transport compound having the formula where R 1 and R 2 are, independently, an (N,N-substituted)arylamine group; R 3 and R 4 are, independently, an alkylsulfonylphenyl group; and X is a linking group having the formula —(CH 2 ) m —, branched or linear, where m is an integer between 0 and 20, inclusive, and one or more of the methylene groups is optionally replaced by an oxygen atom, a carbonyl group, urethane, urea, an ester group, a —NR 5 group, a CHR 6 group, or a CR 7 R 8 group where R 5 , R 6 , R 7 , and R 8 are, independently, H, an alkyl group, or aryl 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.
