We report a new red Ir(III) complex, (btfmp) 2 Ir(acac), with the trifluoromethyl-substituted 2-benzo[b]thiophen-2-yl-pyridine ligand. Efficient red electrophosphorescence with CIE coordinates (x=0.69, y=0.29) independent on current density was observed from the (btfmp) 2 Ir(acac) doped devices. The electroluminescent (EL) spectrum has a maximum at λ max =648nm. Maximum external...
In this study, a new Ir(III) complex containing 2,5-di(4-methoxyphenyl)pyridine ligand was synthesized. The Ir(III) complex of intense green photophosphorescence emission showed its potential for organic electroluminescence (EL). EL devices were fabricated based on the Ir(III) complex. A maximum external quantum efficiency of 9.0% corresponding to a luminance efficiency of 36 cd/A and a peak luminance...
