Abstract
An investigation of five ruthenium complexes with the thermodynamics and kinetics of binding to nanocrystalline TiO2 was made. The ruthenium complexes were structurally different in the number of anchoring carboxy groups attached to coordinated bipyridyl ligands and in the number of auxillary ligands. All the available carboxyl groups were used by the complexes in the dry state with only one monocarboxy or dicarboxy ligand to bind to the surface. The structural difference between the complexes in the five dyes yielded similar maximum coverages ( >100nmol cm-2) on nanocrystalline TiO2 electrodes and exhibited different binding constants.
