发明名称 Derivative with heteroaromatic ring, and light-emitting element, light-emitting device, lighting device, and electronic device using derivative with heteroaromatic ring
摘要 A derivative with a heteroaromatic ring represented by General Formula (G1) is provided. R11 to R20 in the formula independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or an aryl group having 6 to 10 carbon atoms in a ring. J represents a substituted or unsubstituted arylene group having 6 to 12 carbon atoms in a ring. Note that alpha and beta may be bonded to each other to form a carbazole skeleton. Het is a substituent represented by General Formula (S1-1) or (S1-2). In General Formulae (S1-1) and (S1-2), Ar1 to Ar4 are independently a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. R1 is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or an aryl group having 6 to 10 carbon atoms in a ring.
