摘要：

A novel Hg2+-selective chemosensor (3a) with hemicyanine as colorimetric reporting group and Se2N chelating unit as ion binding site was synthesized. The chernosensing behavior and the binding ability of chemosensor 3a with metal ions were investigated via UV-Vis spectrometry. Chemosensor 3a shows specific Hg2+-selectivity in CH3CN-H2O(1:1, volume ratio). The addition of Hg2+ makes the absorption spectrum of chemosensor 3a appear a new band around 410 nm. In addition, the color change of 3a-Hg2+ from rose red to light orange allows naked-eye detection of Hg2+.
