Title:
Compound
Document Type and Number:
Japanese Patent JP6174769
Kind Code:
B2
Abstract:
A novel substance with which an increase in life and emission efficiency of a light-emitting element can be achieved is provided. A carbazole compound having a structure represented by General Formula (G1) is provided. Note that a substituent which makes the HOMO level and the LUMO level of a compound in which a bond of the substituent is substituted with hydrogen deep and shallow, respectively is used as each of substituents in General Formula (G1) (R 1 , R 2 , Ar 3 , and ± 3 ). Further, a substituent which makes the band gap (Bg) and the T1 level of a compound in which a bond of the substituent is substituted with hydrogen wide and high is used as each of the substituents in General Formula (G1) (R 1 , R 2 , Ar 3 , and ± 3 ).
