Abstract

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.
