摘要
A highly sensitive and selective detection of Hg2+ ion with simple salophen probe was developed. In DMSO: water (40:60, v/v) solution, Hg2+ ions coordinate with imine and shows color turn-off from yellow to colorless. Receptor 1 showed its ability for sensing Hg2+ cations sensitively through three channels: colorimetric, UV-vis and fluorescence spectroscopy. Hg2+ ions coordinate to the imine (Receptor 1) through NONO binding site forming 1:1 complex. It exhibits fluorescent 'Turn-on' behavior based on solvent polarity. The detection limit of our receptor with mercury is 1 mu g L-1. (c) 2012 Elsevier B.V. All rights reserved.
