摘要：
Disclosed are an organometallic complex and an electronic device including a light-emitting device having the organometallic complex. The organometallic complex is ortho-metalated by a ligand with a diphenylquinoxaline moiety having an electron-withdrawing group on the phenyl groups. The ability of the organometallic complex to provide a red-emissive light-emitting device with excellent color purity and an extremely long lifetime enables the production of an electronic device with a full-color display portion with excellent color productivity and durability.
