Abstract
Panchromatic photosensitizers having a Formula of ML1L2X were synthesized, wherein M comprises ruthenium atom; X is a monodentate anion; L1 is heterocyclic bidentate ligand having one of formulae listed below:
-
- wherein G2 has one of formulae listed below:
-
- and L2 is a tridentate ligand having a formula listed below:
The substituents R1, R2, R3, R4, R5, R6, R7 of L1 and L2 are the same or different, and represent alkyl, alkoxy, alkylthio, alkylamino, halogenated alkyl, phenyl or substituted phenyl group, carboxylic acid or counter anion thereof, sulfonic acid or counter anion thereof, phosphoric acid or counter anion thereof, amino-group, halogens, or hydrogen. The above-mentioned photosensitizers are suitable to use as sensitizers for fabrication of high efficiency dye-sensitized solar cell.
