Luminescent Ir(III) complexes bearing benzothiazole or benzoxazole-based pincer ligand

This paper discloses crystal structures and photophysical properties of Ir(III) complexes bearing benzothiazole or benzoxazole-based NCN pincer ligands, bidentate NC ligands, and ancillary ligands. The structure of the NCN pincer ligands is a dominant factor for modulating emission wavelength. The OLEDs with the Ir complex showed electroluminescence with 14% external quantum efficiency.168
