Chou, Chun-Cheng published the artcile4,4′,5,5′-tetracarboxy-2,2′-bipyridine Ru(II) sensitizers for dye-sensitized solar cells, Category: chlorides-buliding-blocks, the publication is Inorganic Chemistry (2014), 53(16), 8593-8599, database is CAplus and MEDLINE.
Two Ru(II) sensitizers TCR-1 and TCR-2 bearing four carboxy anchoring groups were prepared using 4,4′,5,5′-tetraethoxycarbonyl-2,2′-bipyridine chelate and 4-(5-hexylthien-2-yl)-2-(3-trifluoromethyl-1H-pyrazol-5-yl)pyridine and 6-t-butyl-1-(3-trifluoromethyl-1H-pyrazol-5-yl)isoquinoline, resp. Dissolution of these sensitizers in DMF solution afforded a light green solution up to 10-5 M, for which their color gradually turned red upon further dilution and deposition on the surface of a TiO2 photoanode due to the spontaneous deprotonation of carboxylic acid groups. These sensitizers were characterized using electrochem. means and structural anal. time-dependent d. functional theory (TDDFT) simulation and were also subjected to actual device fabrication. The as-fabricated DSC devices showed overall efficiencies η = 6.16% and 6.23% vs. their 4,4′-dicarboxy counterparts TFRS-2 and TFRS-52 with higher efficiencies of 7.57% and 8.09%, using electrolyte with 0.2 M LiI additive. Their inferior efficiencies are possibly caused by the combination of blue-shifted absorption on TiO2, inadequate dye loading, and the perpendicularly oriented central carboxy groups.
