A novel water soluble Hg²⁺-selective chemosensor 1 with hemicyanine as fluorescent reporting group and NO₂Se₂ chelating unit as ion binding site was reported. Chemosensor 1 shows a specific Hg²⁺ selectivity to discriminate between Hg²⁺ and chemically close ions in junction with a visible colorimetric change from red to colorless, leading to potential production of both “naked-eye” and fluorometric detection of Hg²⁺ cation.
