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 S2−, EDTA, SCN−, CH3CO2−, Br−, Cl−, F−, H2PO4− and SO42−, which was attributed to the higher stability of inorganic complex between iodide and mercuric(II).
