Abstract

On the basis of the results of frontier orbital considerations, 4-substituted-2′-pyridyltriazoles were designed to serve as ancillary ligands in 2-phenylpyridine main ligand containing heteroleptic iridium (III) complexes that display deep blue phosphorescence emission. The iridium (III) complexes, Ir1–Ir7, prepared using the new ancillary ligands, were found to display structured, highly quantum efficient (Φp= 0.20–0.42) phosphorescence with ...
