Cyclometalated Iridium(III) Complexes Incorporating Aromatic Phosphonate Ligands: Syntheses, Structures, and Tunable Optical Properties.

ABSTRACT: The incorporation of phosphonate ligands into the cyclometalated iridium(III) complexes can not only tune their electronic and optical properties but also provide the possibility of anchoring these molecules on the semiconductor surfaces for further applications. Herein, we report the first examples of mononuclear cyclometallated iridium(III) complexes incorporating phosphonate ligands, namely, [Ir(ppy)₂(HL¹)]·0.5H₂O (1), [Ir(ppy)₂(HL²)]·0.5H₂O (2), [Ir(dfppy)₂(HL¹)] (3), and [Ir(dfppy)₂(HL²)]·3.5H₂O (4) (ppy = 2-phenylpyridine, dfppy = 2-(2,4-difluorophenyl)pyridine, H₂L¹ = 2-pyridylphosphonic acid, H₂L^2<
