Abstract:
A novel water soluble Hg(2+)-selective chemosensor 1 with hemicyanine as fluorescent reporting group and NO(2)Se(2) chelating unit as ion binding site was reported. Chemosensor 1 shows a specific Hg(2+) selectivity and discrimination between Hg(2+) and chemically similar ions in conjunction with a visible colorimetric change from red to colorless, potentially leading to both "naked-eye" and fluorometric detection of Hg(2+) cations.
