Abstract

The peripheral triphenylamine-encapsulated red-emitting iridium(III) complexes have been designed and synthesized. External quantum efficiency over 15% has been realized in single-layer polymer light-emitting diodes, which is the highest ever reported for solution-processed red phosphorescence.
