title: A Hg2+-selective chemodosimeter based on desulfurization of coumarin thiosemicarbazide in aqueous media.
abstract: A fluorescence-enhanced chemodosimeter 1 based on coumarin thiosemicarbazide for Hg(2+) was developed via a Hg(2+)-induced desulfurization reaction. Spectroscopic results reveal that chemodosimeter 1 exhibits high sensitivity and selectivity for Hg(2+) in comparison to common interfering metal ions in aqueous media at room temperature.
