Blue Electrophosphorescence from Iridium(III) Phosphors Bearing Asymmetric Di‐N‐aryl 6‐(trifluoromethyl)‐2H‐imidazopyridin‐2‐ylidene Chelates

Efficient blue phosphors remain a formidable challenge for organic light‐emitting diodes (OLEDs). To circumvent this obstacle, a series of Ir(III)‐based carbene complexes bearing asymmetric di‐N‐aryl 6‐(trifluoromethyl)‐2H‐imidazo[4,5‐b]pyridin‐2‐ylidene chelates, namely, f‐ct6a‒c, are synthesized,...
