Abstract

New cyclometalated iridium(III) complexes, NBEpicIr(Ppy)2 (I) and NBEpicIr(Dfppy)2 (II), were synthesized (NBEpicH = 3-(((1S,4S)-bicyclo[2.2.1]hept-5-ene-2-carbonyl)oxy)picolinic acid, PpyH = 2-phenylpyridine, DfppyH = 2-(2,4-difluorophenyl)pyridine). Complex I was characterized by X‑ray diffraction analysis (CIF file CCDC no. 1878882). Ring opening metathesis polymerization involving compounds I and II and carbazole norbornene monomers gave new iridium-containing copolymers. The photophysical properties of complexes I and II and copolymers based on them were studied.
