Abstract

[Chemical equation presented] On the basis of the mechanism of Hg ²⁺-promoted hydrolysis, a new fluorescent chemodosimeter (Rho-Hg1) is reported for single-selective and parts per billion level-sensitive detection of Hg²⁺ in natural waters, loreover, the fluorescence response of Rho-Hg1 to Hg²⁺ has little interference from sulfur compounds such as cysteine and glutathione and could be used in the Hg²⁺ Imaging In living cells.
