Description

A novel fluorescent probe molecule, 2-(anthracen-9-yl)-1,3-dithiolane (AADT), is designed and synthesized for Hg2+ detection successfully, based on a good aggregation induced emission (AIE) fluorescent mechanism and a specific reaction type. DMF-H2O mixed solvent (Fw 80% V/V) is suitable to disperse AADT for forming 1×10-5 mol·L-1 solution with an AIE-active fluorescence probe system. With the increase of trace Hg (II), the AADT probe shows dual-channel, (turn-off at 429 nm, and turn–on at 511nm) fluorescence probe character. (R2>0.994), which does not interfere each other. The probe demonstrates excellent selectivity, anti-inference properties, and several metal ions and acid ions hardly affect its performance. The LOD of the AADT probe is lower than 2.34×10-8 mol·L-1.
