摘要:A novel compound, a synthesis method thereof, and an organic device including the novel compound are provided. A compound represented by General Formula (G1) is provided. In General Formula (G1), each of R1, R2, and R5 to R7 independently represents any of hydrogen (including deuterium), an alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group having 1 to 60 carbon atoms, and a substituted or unsubstituted heteroaryl group having 1 to 60 carbon atoms. R3 represents a condensed ring composed of 4 to 10 rings containing nitrogen as an element forming the ring, and R4 represents any of a substituted or unsubstituted condensed ring having 1 to 60 carbon atoms, a substituted or unsubstituted aryl group with a molecular weight of 78 or more, and a substituted or unsubstituted heteroaryl group with a molecular weight of 80 or more. At least one of A1 to A3 represents nitrogen, and each of the others represents substituted carbon. Each of substituents of A1 to A3 independently represents any of hydrogen (including deuterium), an alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group having 1 to 60 carbon atoms, and a substituted or unsubstituted heteroaryl group having 1 to 60 carbon atoms.
