BODIPY Appended Crown Ethers: Selective Fluorescence Changes for Hg~(2+) Binding

摘要

Recently, the development of fluorescent chemosensors capable of selective recognition and sensing of metal ions is one of the most challenging fields from the vantage of organic and supramolecular chemistry. The best effective fluorescence chemosensor must convert the event of metal ion recognition by the ionophore into light signals of the fluorophore with high sensitivity and ease of monitoring. In designing sensors, the ionophore linked to the fluorophore should be preliminarily considered because they are responsible for the selectivity and binding efficiency of the whole chemosensors.
