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 α and &bgr; 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.
