Electrophotographic organophotoreceptors with novel charge transport compounds

A charge transport compound having the following formula:

• (R-Q)n-Y
• where R is triarylamine group, diaryl alkylamine group or dialkyl arylamine group;
• Q comprises an aliphatic or aromatic hydrazone linking group wherein the hydrazone linking group has the formula:
• where Z is an alkyl group or an aryl group;
• and X is —(CH2)m— where m is an integer between 0 and 20;
• n is 2;
• and
• Y has the formula:
• where A1, A2, A3, A4, A5, A6, A7, and A8 comprise, each independently, H, an aryl group, a heterocyclic group, a hydroxyl group, a thiol group, a cyano group, a nitro group, a carboxyl group, an amino group, a halogen, an acyl group, an alkoxy group, an alkylsulfanyl group, an alkenyl group, an alkynyl group, a part of a ring group, such as cycloalkyl groups, heterocyclic groups, and a benzo group, or an alkyl group where one or more of the hydrogens of the alkyl group is optionally replaced by an aromatic group, a hydroxyl group, a thiol group, a carboxyl group, an amino group, or a halogen.
