CARBAZOLE DERIVATIVE, LIGHT-EMITTING ELEMENT MATERIAL OBTAINED BY USING CARBAZOLE DERIVATIVE, LIGHT-EMITTING ELEMENT, AND ELECTRONIC DEVICE

摘要

It is an object to provide a carbazole derivative which is useful as a raw material for forming a light-emitting element material which has resistance to repeated oxidation reactions. It is an object to provide a carbazole derivative represented by a general formula (G-1). In the general formula (G-1), each of Ar1 and Ar2 represents an aryl group having 1 to 12 carbon atoms such as phenyl, biphenyl, or naphthyl. Also, R1 represents any one of hydrogen, an alkyl group having 1 to 4 carbon atoms such as methyl, ethyl, or tert-butyl, and an aryl group having 6 to 12 carbon atoms such as phenyl, biphenyl, or naphthyl. Further, the aryl group may have a substituent, or is not required to have a substituent. General formula (G-1) is inserted.
