2-Ethyl-3,5,7-trinitrofluorenonimine derivative and use as charge transport

摘要

The present invention provides a novel trinitrofluorenonimine derivative represented by the general formula (1): <CHEM> wherein R<0> is an alkyl group; and R<1>, R<2>, R<3>, R<4> and R<5> 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. <IMAGE>
