This invention relates to a novel organophotoreceptor that includes:
(a) a charge transport compound having the formula
1
where n is an integer from 0 to 1 inclusive;
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);
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.
