Provided is an organometallic complex which emits light with a short wavelength and has high emission efficiency and high heat resistance. The organometallic complex includes a central metal; and a first ligand, a second ligand, a third ligand, and a fourth ligand which are coordinated to the central metal. The first ligand includes a triazole skeleton including nitrogen bonded to the central metal. The second ligand includes an indolo[3,2-b]carbazole skeleton whose 6-position is bonded to the central metal or a pyrido[2,3-b:6,5-b′]diindole skeleton whose 6-position is bonded to the central metal. The third ligand includes a benzene skeleton whose carbon is bonded to the central metal. The fourth ligand includes a pyridine skeleton whose nitrogen is bonded to the central metal or a benzene skeleton whose carbon is bonded to the central metal.
提供的是一种有机金属配合物,它发射具有短波长的光,并具有高发射效率和高耐热性。该有机金属配合物包括一个中心金属;以及与中心金属配位的第一配体、第二配体、第三配体和第四配体。第一配体包括一个包含与中心金属键合的氮的三唑骨架。第二配体包括一个6位与中心金属键合的indolo[3,2-b]carbazole骨架或一个6位与中心金属键合的pyrido[2,3-b:6,5-b′]diindole骨架。第三配体包括一个碳与中心金属键合的苯骨架。第四配体包括一个氮与中心金属键合的吡啶骨架或一个碳与中心金属键合的苯骨架。
