Abstract
A series of bis-cyclometalated iridium(III) complexes, [Ir(LH)2(H2dcbpy)][PF6] (1), [Ir(LMe)2(H2dcbpy)][PF6] (2), and [Ir(LPh)2(H2dcbpy)][PF6] (3), where LH = 1-H-2-phenylbenzimidazole, LMe = 1-methyl-2-phenylbenzimidazole, LPh = 1,2-diphenylbenzimidazole, and H2dcbpy = 2,2′-bipyridine-4,4′-dicarboxylic acid, has been synthesized and fully characterized by elemental analysis, 1H and 31P NMR spectroscopy, mass spectrometry, and single-crystal X-ray analysis. The complexes show strong luminescence in the yellow–orange region in ethanol at room temperature (quantum yield is up to 22 %), and absorb light up to 550 nm with molar absorptivities of 1500–2000 M–1 cm–1. Complexes 1 and 2 possess very similar optical properties, whereas the introduction of the phenyl ring (complex 3) causes a hypsochromic shift (≈ 30 nm) of the luminescent maximum as well as resulting in an almost 50 % increase in the extinction coefficient at 490 nm compared with 1 and 2. A dye-sensitized solar cell (DSSC) based on complex 3 exhibits a short-circuit photocurrent of 2.8 mA cm–2, an open-circuit photovoltage of 0.44 V, and a power conversion efficiency of 0.7 %.
