TL;DR: The selectivity and sensitivity of two colorimetric sensors based on the ruthenium complexes N719 and N749 are described, found that mercury ions coordinate reversibly to the sulfur atom of the dyes' NCS groups, which induces a color change in the dye groups at submicromolar concentrations of mercury.
