A bipolar homoleptic iridium dendrimer composed of diphenylphosphoryl and diphenylamine dendrons for highly efficient non-doped single-layer green PhOLEDs

摘要

A novel second-generation bipolar iridium(III) dendrimer featured with diphenylphosphoryl and diphenylamine groups has been designed and synthesized. A maximum current efficiency of 21.6 cd A(-1) has been realized, which is among the highest ever reported for single-layer self-host green PhOLEDs.
