Ratiometric fluorescence chemodosimeter for mercuric ions through the Hg(II)-mediated propargyl amide to oxazole transformation

摘要

A coumarin-based alkyne was developed as a fluorescent chemodosimeter for the selective detection of mercuric ion. The probe showed a highly selective and ratiometric response toward Hg(II) ion over other metal ions with a micromolar level of limit of detection.
