4,5-bis(2'-cyanoethylthio)-1,3-dithiole-2-thione (dmit) was treated with sodium methoxide to deprotect one 2-cyanoethyl group, affording mono-thiolate of dmit. The generated mono-thiolate was trapped by 9, 10-dicholormethylene anthracene to yield a novel triad fluorescent chemodosimeter with DMIT and anthracene units. The triad reacted with Hg(OAc)2 to yield a strongly fluorescent compound 4 and a complex 5 of dmit. So the triad could selectively recognize Hg2+ by the unique properties of compound 4. Fluorescence properties of the triad were further explored in ionic liquid. The experiment results showed that fluorescence intensity of the triad became more strengthen with amounts of ionic liquid.

[10] Fluorescence quantum efficiencies were determined by comparing the integrated fluorescence spectra of the sample with that of a standard (9,10-diphenylanthracene in THF (φf=1.00).
