Panchromatic photosensitizers having a formula of ML1L2X were synthesized, wherein M is ruthenium; X is a monodentate anion; L1 is heterocyclic bidentate ligand having one of formula listed below: wherein G2 has one of formula listed below: and L2 is a tridentate ligand having a formula listed below: The R1, R2, R3, R4, R5, R6, R7 substituents of L1 and L2 ligands are the same or different and represent alkyl, alkoxy, alkylthio, dialkylamino, halogenated alkyl, phenyl or substituted phenyl group, carboxylic acid group or acid radical salt thereof, sulfonic acid group or acid radical salt thereof, phosphoric acid group or acid radical salt 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. |
