Abstract

An efficient and stable red phosphorescent organic light emitting diode was developed using a tetradentate cyclometalated platinum complex. Devices employing the phosphorescent molecule, platinum(II)-9-(4-methylpyridin-2-yl)-2- (3-(quinolin-2-yl)phenoxy)-9H-carbazole (PtON11Me), yielded high external quantum efficiencies and high operational lifetimes. A maximum EQE of 12.5% and color coordinates CIE (x = 0.61, y = 0.36) was achieved in devices employing efficient hole blocking and transporting materials and a high operational lifetime of T_0.97 ∼ 3200 h was achieved in devices utilizing electrochemically stable hole blocking and transporting materials.
