Abstract: An organic compound is represented by General Formula (G1). In the formula, each of R1 to R4 independently represents any of hydrogen (including deuterium), a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 6 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 carbon atoms, and a substituent represented by General Formula (G1-1). Each of R5 to R8 independently represents any of hydrogen (including deuterium), a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 6 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 carbon atoms, and a substituent represented by General Formula (G1-3). At least one of R5 to R8 represents a substituent represented by General Formula (G1-3).

Abstract: 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.

Abstract: An organic compound with a long lifetime and high emission efficiency is provided. An organic compound represented by General Formula (G1) is provided. In the formula, any one of X1 to X4 represents N, another one represents C, and the others represent C or N. Any one of C is bonded to a group represented by General Formula (r1), and the others are bonded to hydrogen (H), an alkyl (R) group, a cycloalkyl (Cy) group, an aryl (Ar) group, or a heteroaryl (Het) group. Ar1 represents an aromatic hydrocarbon, and is fused to an adjacent ring at a given site. When Ar1 represents a benzene ring, the benzene ring includes an Ar group or a Het group. Q and Z represent O or S. Any of R31 to R34 represents a bond to any one of X1 to X4, and the others represent H, an R group, a Cy group, an Ar group, or a Het group. Any one of R35 to R38 represents a polycyclic ring aromatic hydrocarbon group or a Het group, and the others represent H, an R group, a Cy group, an Ar group, or a Het group.
