The present invention provides organophotoreceptors comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising:
(a) a charge transport material having the formula
where
n is an integer between 2 and 6, inclusive;
R1 and R2 are, independently, H, halogen, carboxyl, hydroxyl, thiol, cyano, nitro, aldehyde group, ketone group, an ether group, an ester group, a carbonyl group, an alkyl group, an alkaryl group, or an aryl group;
X is a linking group having the formula -(CH2)m-, branched or linear, where m is an integer between 0 and 20, inclusive, and one or more of the methylene groups can be optionally replaced by O, S, C=O, O=S=O, urethane, urea, an ester group, a NR3 group, a CHR4 group, or a CR5R6 group where R3, R4, R5, and R6 are, independently, H, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group;
Y comprises a bond, C, N, O, S, a branched or linear -(CH2)p- group where p is an integer between 0 and 10, an aromatic group, a cycloalkyl group, a heterocyclic group, or a NR7 group where R7 is hydrogen atom, an alkyl group, or aryl group, wherein Y has a structure selected to form n bonds with the corresponding X groups; and
Z is a fluorenylidene group; and
(b) a charge generating compound.
Corresponding electrophotographic apparatuses and imaging methods (processes) are described, as are corresponding charge transport materials.
