Estimating the term…
A novel organometallic complex that is highly convenient, useful, or reliable, and a light-emitting device are provided. The organometallic complex is represented by General Formula (G2). In General Formula (G2), each of R1 to R6, R8 to R22, and R31 to R34 independently represents hydrogen (including deuterium), an alkyl group having 1 to 10 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 18 carbon atoms, at least one of R31 to R34 represents an alkyl group having 1 to 10 carbon atoms or a substituted or unsubstituted aryl group having 6 to 18 carbon atoms, and n is an integer of 1 to 4.
