- In this paper, we present the synthesis and characterization of a new highly phosphorescent cyclometalated Ir(III) complex with a silane-based dendritic substituent. The Ir(III) complex showed 74 ± 3% of absolute phosphorescence quantum efficiency in the film state. In addition, efficient electrophosphorescence (32.8 cd A–1) employing an Ir(III) complex–poly(N-vinylcarbazole) system device is observed. Study of a series of electroluminescent, spectroscopic, and electrochemical data of the Ir(III) complex and the reference Ir(ppy)3 reveals superior performance of the new Ir(III) complex.
