Novel Benzothiazole-Based Highly Selective Ratiometric Fluorescent Turn-On Sensors for Zn and Colorimetric Chemosensors for Zn, Cu, and Ni Ions.

Metal ions play a very important role in environmental as well as biological fields. The detection of specific metal ions at a minute level caught much attention, and hence, several probes are available in the literature. Even though benzothiazole-based molecules have a special place in the medicinal field, only very few chemosensors are reported based on this moiety.
