Iridium(iii) dipyridylamine complexes: synthesis, characterization and catalytic activities in photoredox reactions

Two new series of cyclometalated iridium(III) complexes bearing a dipyridylamine as the N^N ligand have been prepared and fully characterized. After investigation of their photophysical properties, their catalytic activities have been evaluated in a model photoredox reaction and compared with the commercially available [Ir(ppy)2(dtbbpy)][PF6] complex.
