Iridium(III) Phosphors–Bearing Functional 9‐Phenyl‐7,9‐dihydro‐8H‐purin‐8‐ylidene Chelates and Blue Hyperphosphorescent OLED Devices

Herein, a series of blue‐emitting Ir(III) phosphors is reported based on the cyclometalating N‐heterocyclic carbenes (NHCs), in which the typical benzimidazolylidene entity is now replaced by a new 7,9‐dihydro‐8H‐purin‐8‐ylidene unit. The two extra‐nitrogen atoms of benzimidazolylidene entity that a...
