title: Ratiometric detection of mercury ions in water: accelerated response kinetics of azo chromophores having ethynyl ligand tethers.
abstract: The metal-induced intramolecular cyclization reaction of an azo dye was exploited for the colorimetric detection of mercury ions in water. The molecular probe 3 responds selectively to nM-level Hg(II) ions in neutral aqueous solutions.
