A novel β-diketone ligand bearing a thiophene moiety and an anchoring Ph-COOCH3 unit has been designed, prepared and used in synthesis of cyclometalated benzimidazole-based iridium(III) complexes for application in dye-sensitized solar cells (DSSC). The replacement of traditional 4,4′-dicarboxy-2,2′-bipyridine by this aromatic β-diketone results in excellent tuning the redox potentials and excited state properties of these IrIII complexes, one of which exhibits good efficiency when used as a dye in DSSC. All the complexes demonstrate reversible redox behavior, with oxidation potentials (Ir4+/Ir3+) strongly depending on the electron-donor/withdrawing nature of the substituents in the cyclometalated ligands. Surprisingly, the latter has just a little effect on their luminescence spectra, in which structured emission bands are observed Time-resolved spectroscopic studies in combination with DFT calculations show that the complexes emit light by mixed 3MLCT-3LC excited states predominantly composed of the diketone ligand-centered triplet state. The experimental part of the paper was very detailed, including the reaction process of 3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0Reference of 3-(Methoxycarbonyl)benzoic acid)
3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Reference of 3-(Methoxycarbonyl)benzoic acid Polyesters are important plastics, with monomers linked by ester moieties.
