The synthesis and luminescence study of a new platinum quinoxaline complex are reported. The complex, [(DPQ)Pt(acac)](DPQ=2, 3-diphenylquinoxaline, acac=2, 4-pentanedione) was synthesized by reaction of 2, 3-diphenylquinoxaline with K2PtCl4 and shows strong 1MLCT (singlet metal to ligand charge-transfer) and 3MLCT (triplet metal to ligand charge-transfer) absorption at 442 and 485 nm, respectively. Organic light emitting diode (OLED) with a configuration of [ITO/NPB(21 nm) /NPB∶7% (DPQ)Pt(acac)(17.5 nm) /BCP(7 nm)/ Alq3(21 nm)/ Mg∶Ag(10∶1)(120 nm)/Ag(10 nm)] (ITO: indium tin oxide; NPB: 4,4′-bis[N-(1-naphthyl)-N-phenyl-amino] biphenyl; BCP: 2, 9-dimethyl-4, 7-diphenyl-1, 10-phenanthroline; Alq3: tris(8-hydroxyquinoline) aluminum) shows a red emission at 632 nm with an external quantum efficiency of 0.66% at 7.2 V and brightness of 1516 cd·m-2 at 21 V. The power efficiency of the device was 0. 26 lm·W-1 at 7.2 V.
