Amidate-assisted bis(2-quinolyl)phenyl iridium(III) complexes: Synthesis, structures, photophsical characterization, DFT calculations and their application in homopolymerization

•Amidate iridium(III) bis(2-quinolyl)phenyl compounds with four-member ring structure.•Amidate influenced absorption and emission energies of the Ir complexes.•These Ir complexes were investigated by DFT calculations.•Amidate iridium(III) compound has been employed for polymerization reaction.

The synthesis, characterization by X-ray crystallography, photophysical properties and DFT calculations of bis(2-quinolyl)phenyl iridium complexes are reported here. The quinolyl-substituted iridium(III) compounds, which have amidate ancillary ligand, formed four-membered ring structure and have been employed for polymerization reaction and gave the metal-containing amide homopolymers.
