Abstract: A benzofuropyrimidine derivative or benzothienopyrimidine derivative that is a novel organic compound is provided. An organic compound represented by General Formula (G1) below.




Q represents oxygen or sulfur. Ar1, Ar2, Ar3, and Ar4 each independently represent an aromatic hydrocarbon ring, and the number of carbon atoms included in the aromatic hydrocarbon ring is 6 to 25. m and n are each 0 or 1. A is a group having 12 to 100 carbon atoms in total and includes one or more of a benzene ring, a naphthalene ring, a fluorene ring, a phenanthrene ring, a triphenylene ring, a heteroaromatic ring including a dibenzothiophene ring, a heteroaromatic ring including a dibenzofuran ring, a heteroaromatic ring including a carbazole ring, a benzimidazole ring, and a triphenylamine structure.

Abstract: A benzofuropyrimidine derivative or a benzothienopyrimidine derivative that is a novel organic compound is provided. The organic compound has a benzofuropyrimidine skeleton or a benzothienopyrimidine skeleton and is represented by General Formula (G1) below. In General Formula (G1), Q represents oxygen or sulfur. Each of A1 and A2 independently represents a substituted or unsubstituted polycyclic aromatic hydrocarbon. Furthermore, m represents any one of integers from 0 to 4. Furthermore, n represents any one of integers from 1 to 4. Each of R1 to R12 independently represents any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 7 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.
