摘要: Seven unsymmetrical heptamethine dyes with carboxylic acid functionality were synthesized and characterized. These near-infrared exhibit outstanding photophysical properties depending on their heterocyclic moieties molecular structure. As proof of principle, the used as photosensitizers in dye-sensitized solar cells. Using most promising dye, an overall conversion efficiency 1.22% almost colorless cell achieved.
