Organometallic Complex, Light-Emitting Element, Light-Emitting Device, Electronic Device, and Lighting Device

摘要

As a novel substance having a novel skeleton, an organometallic complex with high emission efficiency is provided. The organometallic complex includes a metal and a ligand. The metal is iridium or platinum. The ligand includes a 5H-pyrimido[5,4-b]indole skeleton and an aryl group bonded to the 4-position of the 5H-pyrimido[5,4-b]indole skeleton. The 3-position of the 5H-pyrimido[5,4-b]indole skeleton and the aryl group are bonded to the metal. In the formula, M represents iridium or platinum. In addition, Ar represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and each of R1 to R6 independently represents hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 10 carbon atoms.
