Trinitrofluoroenonimine derivative and electrophotosensitive material using the same

摘要

The present invention provides a novel trinitrofluorenonimine derivative represented by the general formula (1): <IMAGE> (1) wherein R0 is an alkyl group; and R1, R2, R3, R4 and R5 are the same or different and indicate a hydrogen atom, an alkyl, an alkoxy, an aryl, an aralkyl, a halogen atom or an alkyl halide. This derivative is superior in electron transferring capability and compatibility with binding resin. Accordingly, an electrophotosensitive material comprising this derivative as an electron transferring material is superior in sensitivity.
