Hg2+ -selective chromogenic and fluorogenic chemodosimeter based on thiocoumarins.
The highly selective chemodosimetric behavior of thiocoumarins toward Hg(2+) ions was investigated; significant chromogenic and fluorogenic signaling of Hg(2+) ions occurs from the transformation of thiocoumarin to coumarin by Hg(2+)-induced selective desulfurization.
