Mixed-carbene cyclometalated iridium complexes with saturated blue luminescence.

ABSTRACT: Cyclometalated iridium complexes have emerged as top-performing emitters in organic light-emitting diodes (OLEDs) and other optoelectronic devices. A persistent challenge has been the development of cyclometalated iridium complexes with deep blue luminescence that have the requisite color purity, efficiency, and stability to function in color displays. In this work we report a new class of cyclometalated iridium complexes with saturated blue luminescence. These complexes have the general structure Ir(C^C:^NHC)₂(C^C:^ADC), where C^C:^NHC is an N-heterocyclic carbene (NHC) derived cyclometalating ligand and C^C:^ADC is a different type of cyclometalating ligand featuring an acyclic diaminocarbene (ADC). The complexes are prepared by a cascad
