  • Organophotoreceptors for electrophotography featuring novel charge transport compounds
    Patent number: 6140004
    Abstract: An organic photoreceptor that includes:(a) a charge transport compound having the formula ##STR1## where n is an integer between 2 and 6, inclusive; R.sup.1 and R.sup.2, independently, are an alkyl group, a cycloalkyl group, or an aryl group, or R.sup.1 and R.sup.2 combine with the nitrogen atom to form a ring;Y is a bond, a carbon atom, a --CR.sup.3 group, an aryl group, a cycloalkyl group, or a cyclosiloxyl group;R.sup.3 is hydrogen, an alkyl group, or an aryl group; andX is a linking group having the formula --(CH.sub.2).sub.m -- wherein m is an integer between 4 and 10, inclusive, and one or more of the methylene groups is optionally replaced by an oxygen atom, a carbonyl group, or an ester group;(b) a charge generating compound; and(c) an electroconductive substrate.
    Type: Grant
