CARBAZOLE DERIVATIVE, MATERIAL FOR LIGHT-EMITTING ELEMENT PREPARED BY USING IT, LIGHT-EMITTING ELEMENT, AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a carbazole derivative useful as a material for producing a material for a light-emitting element which is resistant to the repetition of an oxidation reaction. SOLUTION: The carbazole derivative is represented by general formula (G-1) (wherein Ar1and Ar2are each a 6-12C aryl group such as a phenyl, biphenyl, or naphthyl group; and R1is hydrogen, a 1-4C alkyl group such as methyl, ethyl or tert-butyl group, or a 6-12C aryl group such as a phenyl, biphenyl, or naphthyl group, provided that the aryl group may have a substituent or may be non-substituted).
