HgII-Selective Fluorescent Indicator

HgII-Selective Fluorescent Indicator

Author: ChemViews

Seul-Bi Kim and Dong-Gyu Cho, Inha University, Incheon, Korea, developed a simple fluorescent indicator that undergoes a new type of reaction only in the presence of HgII. The HgII-detection mechanism was verified by using LC-MS and NMR techniques. The reaction involves an Hg-selective hydrolysis/decarboxylation sequence, which has not been used for any metal detection. The present fluorescent indicator requires minimal synthesis effort in a single step.

Overall, this simple compound synthesized in a single step can achieve higher selectivity and sensitivity toward HgII over other metal ions.
