title: Selective recognition iodide in aqueous solution based on fluorescence enhancement chemosensor.
abstract: A novel and simple fluorescence enhancement method for selectively sensing iodide was proposed based on metal complex formation between mercuric(II) ion with fluorophore (p-((dimethylamino)benzylidene)thiosemicarbazide, 1) and with anion in aqueous solution. The 1-Hg complex was found to show selectively and sensitively fluorescence enhancement response toward iodide over than S(2-), EDTA, SCN-, CH(3)CO(2-), Br-, Cl-, F-, H2PO4- and SO4(2-), which was attributed to the higher stability of inorganic complex between iodide and mercuric(II).
