- Abstract:
- A new ruthenium(II) sensitizer platform featuring a readily prepared 1,2,3-triazolate-based tridentate ligand is reported. On account of the anionic 1,2,3-triazolates, the new sensitizer features a broad absorption of visible light, metal-to-ligand charge transfer transitions directed toward the anchoring ligand, relatively long excited-state lifetime, and redox potentials suitable for applications in the dye-sensitized solar cell. Accordingly, the new thiocyanate-free sensitizer achieves power-conversion efficiencies that approach the ones of a thiocyanate-containing benchmark sensitizer.
