Description
Two new heteroleptic ruthenium(II) photosensitizers that contains 2,2′;6,2′′-terpyridine with extended π-conjugation with donor groups, a 4,4′-dicarboxylic acid-2,2′-bipyridine anchoringligand and a thiocyanate ligand have been designed, synthesized and fully characterized by CHN, mass spectrometry, UV-vis and fluorescence spectroscopies and cyclic voltammetry. The new sensitizers have either 3,5-di-tert-butyl phenyl (m-BL-5) or triphenylamine (m-BL-6) groups, where the molar extinction coefficient of both the sensitizers is higher than the analogous ruthenium dyes. Both the sensitizers were tested in dye-sensitized solar cells using two different redox electrolytes.
