Coumarinyl thioether Schiff base as a turn-on fluorescent Zn(<scp>ii</scp>) sensor and the complex as chemosensor for the selective recognition of ATP, along with its application in whole cell imaging

Abstract

A Zn²⁺ sensor, coumarinyl thioether Schiff base shows the LOD 0.068 μM. The fluorogenic complex, [ZnL] recognizes ATP in presence of other anions and the LOD, 6.7 μM, is the lowest in literature. Ligand is used for fluorescence cell imaging process.
