Cyclometallated 1,2,3-triazol-5-ylidene iridium(III) complexes: synthesis, structure, and photoluminescence properties

A series of heteroleptic cyclometallated 1,2,3-triazol-5-ylidene Ir III complexes were synthesized and structurally characterized. These new complexes demonstrated photoluminescence in green (550 nm) and cyan (499, 496 nm) regions. Their photophysical properties were rationalized using DFT calculations. © 2019
