CARBAZOLE COMPOUND, AND FUNCTIONAL MATERIAL AND LIGHT EMITTING ELEMENT THAT INCLUDE SAME
Document Type and Number:
WIPO Patent Application WO/2022/045325
Kind Code:
A1
Abstract:
An indolo[3,2,1-jk]carbazole compound according to one aspect of the present invention is represented by formula (1). (In this general formula, R1, R2, R3, and R4 each independently represent a hydrogen atom, a C1-12 alkyl group, a phenyl group, a cyano group, a polycyclic aromatic hydrocarbon group, or a hetero aromatic ring group. Additionally, in this formula, X1, X2, and X3 each independently represent a nitrogen atom or a hydrogen substituted carbon atom, but at least one of X1, X2, and X3 is a nitrogen atom.)
