摘要：

A Hg2+ coordinate complex of a 1,4-dioxa-7,13-dithia-10-azacyclo-pentadecane-BODIPY dyad 1 recognises L-cysteine (cys), selectively, over other amino acids via reversible complexation/decomplexation and show switching of fluorescence upon sequential addition of Hg2+ and cys solutions. Further, addition of the dyad to the Hg2+ cholate hydrogel is attended by a gel to sol phase transition.
