Abstract:
Provided as a novel substance is a long-lifetime organometallic iridium complex emitting yellow light with high emission efficiency. The organometallic iridium complex is represented by General Formula (G1) and has a structure in which a phenyl group whose 2-position and 6-position are each substituted by an alkyl group is bonded to the 4-position of pyrimidine. In General Formula (G1), R1 and R2 each independently represent a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms.
