Fluorescence Light-up Sensing of Hg2+ Ion in Water.
Fluorescent probe for Hg2+ based on meta-di-4-methylpyridyl benzene (m-DPB) core.
Displays a high selectivity and sensitivity (1 μM) for Hg2+ with a switch-on fluorescence response.
A 1:1 probe-metal complexation with high binding constant.
Selective sensing of Hg2+-ion with low detection limit.
