QUINONE BASED COMPOUND, PHOTOSENSITIVE ARTICLE FOR ELECTROPHOTOGRAPHY AND ELECTROPHOTOGRAPHIC DEVICE USING THE SAME

摘要

A quinone-based compound having a structure represented by the following general formula (I): [wherein, R<1> to R<4>, R<5> and R<6 >represent an alkyl group or the like, an aryl group or the like, and a halogen atom or the like, respectively, X represents a sulfur atom or an oxygen atom, n represents an integer of 0 to 3, and when n is 2 or 3, R<6 >may combine with one another to form a ring or a condensed ring]; a photosensitive article for an electrophotography containing the compound in the photosensitive layer thereof; and an electrophotographic device using the article. The quinone-based compound is excellent in electron transporting function and thus is useful for a photosensitive article for an electrophotography and an organic EL application, and the photosensitive article is excellent in electric characteristics and is stable also when used repeatedly.
