摘要：
本发明涉及一种有机化合物、发光元件、发光器件、电子器件和照明器件。提供了一种能使发光元件的寿命和发射效率增加的新物质。提供了具有通式(G1)表示的结构的咔唑化合物。应注意，分别使用能使化合物的HOMO能级深和使LUMO能级浅的取代基作为通式(G1)中的各取代基(具体为R1,R2,Ar3和α3)，所述化合物中取代基的键被氢取代。此外，使用能使化合物的带隙(Bg)宽和T1能级高的取代基作为通式(G1)中的各取代基(具体为R1,R2,Ar3和α3)，所述化合物中取代基的键被氢取代。
摘要（英）：

The invention relates to an organic compound, a light-emitting element, a light-emitting device, an electronic device, and a lighting device. According to the invention, 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 [alpha]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 [alpha]3 ).
