摘要

A series of new thionaphthalimide derivatives were prepared, and their Hg~(2+)-selective signaling behavior was investigated in aqueous acetonitrile solution. A monothionaphthalimide (anti) exhibited pronounced Hg~(2+)-selective chromogenic signaling behavior through a solution color change from red to yellow, which was easily detectable by eye. It (anti) also showed prominent off-on type Hg~(2+)-selective fluorescent signaling behavior. The signaling is due to the Hg~(2+)-assisted desulfurization of the thioimide to its imide structure. The presence of other common metal ions did not interfere with the Hg~(2+)-signaling of the monothionaphthalimide (anti). The detection limit of monothionaphthalimide (anti) for the determination of Hg~(2+) ions in 30% aqueous acetonitrile was estimated to be 2.7 礛.
