NAPHTHALENETETRACARBOXYDIIMIDE DERIVATIVE, AND ELECTROPHOTOGRAPHIC PHOTOCONDUCTIVE MATERIAL COMPRISING THE SAME AS CHARGE TRANSFERRING MATERIAL

摘要

PURPOSE: Provided are a naphthalenetetracarboxydiimide derivative compound having improved electron transferring power, excellent solubility in an organic solvent and good compatibility with a binder resin, and an electrophotographic photoconductive material comprising the same as a charge transferring material. CONSTITUTION: The naphthalenetetracarboxydiimide derivative compound is represented by the formula 2, wherein each of R1, R2 and R3 is independently any one selected from the group consisting of hydrogen; a halogen atom; a substituted or non-substituted C1-C20 alkyl group; a substituted or non-substituted C1-C20 alkoxy group; a substituted or non-substituted C6-C30 aryl group; and a substituted or non-substituted C7-C30 aralkyl group. The electrophotographic photoconductive material includes a substrate and a photoconductive layer on the substrate, wherein the photoconductive layer comprises a charge-generating material and a charge-transferring material containing the above naphthalenetetracarboxydiimide derivative compound.
