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 Ar
1
and Ar
2
represents an aryl group having 1 to 12 carbon atoms such as phenyl, biphenyl, or naphthyl. Also, R
1
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.
本发明旨在提供一种卡巴唑衍生物,其可用作形成耐受重复氧化反应的发光元素材料的原材料。本发明旨在提供一种由通式(G-1)表示的卡巴唑衍生物。在通式(G-1)中,Ar1和Ar2各自表示具有1至12个碳原子的芳基基团,例如苯基、联苯基或萘基。此外,R1表示氢、具有1至4个碳原子的烷基基团,例如甲基、乙基或叔丁基,以及具有6至12个碳原子的芳基基团,例如苯基、联苯基或萘基。此外,芳基基团可以具有取代基,也可以不需要取代基。
