Abstract To concurrently realize large electroluminescence dissymmetry factor and high device efficiency remains a formidable challenge in the development of circularly polarized organic light‐emitting diode (CP‐OLED). In this work, by introducing famous chiral resource R ‐camphor, two green iridium(III) isomers Λ/Δ‐Ir‐( ‐camphor) containing dual stereogenic centers at iridium ancillary ligand, are efficiently synthesized. Benefiting from their phosphorescence quantum yields (≈93%) obvious...

Abstract Due to the high quantum efficiency and wide scope of emission colors, iridium (Ir) (III) complexes have been widely applied as guest materials for OLEDs (organic light-emitting diodes). Contrary well-developed Ir(III)-based red green phosphorescent complexes, efficient blue emitters are rare reported. Like development LED, absence stable hinders practical application OLEDs. Inspired by this, we designed two novel ancillary ligands phenyl(pyridin-2-yl)phosphinate (ppp)...
