Abstract

A new deep green-emitting material, a 3,5-bis(trifluoromethyl)phenylene-substituted iridium(III) complex, fac-tris[2-(3′,5′-bis(trifluoromethyl)biphenyl-3-yl)pyridine]iridium (Ir(mtfppy)3), was synthesized. Introducing bulky 3,5-bis(trifluoromethyl)phenylene to the metaposition of pyridyl-phenyl results in blue-shifted narrow emission compared to that of Ir(ppy)3. The organic light-emitting diode (OLED) based on Ir(mtfppy)3 shows a maximum external quantum efficiency (EQE) of 23.2% with the CIE coordinates of (0.26, 0.63) without strong microcavity effect.
