Neutral 2-phenylbenzimidazole-based iridium(iii) complexes with picolinate ancillary ligand: tuning the emission properties by manipulating the substituent on the benzimidazole ring

Abstract

A luminescence study with ab initio calculations that allow us to determine the lowest emitting excited state of a series of neutral Ir(iii) complexes with 2-phenylbenzimidazole cyclometallating ligand.
