ResumoA simple 4-Methyl-7-hydroxy-8-formyl Coumarin (CS) serves as a selective chemosensor for Mg2+ in the presence of alkali and alkaline earth metal ions. It showed a significant fluorescence enhancement towards Mg2+. The receptor CS exhibited a good binding constant and lowest detection limit for Mg2+. The variation of emission signal exists via of reversible chelation enhanced fluorescence (CHEF) with this inherent quenching metal ion.
