The synthesis and luminescent study of a new iridium pyrazine complex are reported. The iridium complex [Ir(MDPP)2(acac)] (MDPP=5-methyl-2,3-diphenylpyrazine, acac=acetylacetone) shows strong 1 MLCT (singlet metal-to-ligand charge-transfer) and 3 MLCT (triplet metal to ligand charge-transfer) absorption at 386 and 507 nm, respectively. Organic light emitting device (OLED) with a configuration of ITO/NPB (30 nm)/NPB: 7% (wt.) Ir(MDPP) 2 (acac) (25 nm)/BCP (10 nm)/Alq 3 (30 nm)/Mg:Ag (mass ratio 10:1)120 nm/Ag(10 nm) exhibits an external quantum efficiency of 6.02% (power efficiency 9.89 lm W −1 ) and a maximum brightness of 78,924 cd m −2 . The device also shows high color purity with a maximum peak at 576 nm without any shoulder.
