The synthesis and characterization of a new family of homoleptic Ir(III) tris(pyridylazolate) complexes, in anticipation of seeing the symmetry restriction on such systems, i.e., showing efficient blue phosphorescence with better color chromaticity is reported. The synthetic scheme, from the isolated intermediate and x-ray analyses, rendered solely meridional structures. The results leads to propose an unusual intra-ligand charge transfer to ligand-to-ligand charge transfer conversion, i.e., an electron transfer like process (vide infra), for which the LLCT lowers the luminous efficiency and results in an unwanted bathochromatic shift.
