Panchromatic photosensitizers having a Formula of ML 1 L 2 X were synthesized, wherein M represents ruthenium atom; X represents a monodentate anion; L 1 is heterocyclic bidentate ligand having one of formulae listed below: n nwherein G 2 has one of formulae listed below:n n nand L 2 is a tridentate ligand having a formula listed below:n n n n n n n n n n n Substituents R 1 , R 2 , R 3 and R 4 of L 1 are the same or different and are selected from the group consisting of hydrogen, halogen, amino-group alkyl, alkoxy, alkylthio, alkylamino, halogenated alkyl, phenyl and substituted phenyl group. Substituents R 5 , R 6 and R 7 of L 2 are the same or different and are selected from the group consisting of carboxylic, carboxylate, sulfonic acid, sulfonate, phosphoric acid and phosphate. The above-mentioned photosensitizers are suitable to use as sensitizers for fabrication of high efficiency dye-sensitized solar cell. |
