Study on a New Coumarin Derivative as Fluorescent Probe for Hg²⁺ Ions

Abstract:

A new coumarin derivative L was synthesized and characterized by ¹H NMR, ¹³C NMR, IR and mass spectrum. UV-Vis and fluorescence emission spectra of L without or with different anions (NO₂, F, Cl, HSO₃, HSO₄, AcO or NO₃) or metal ions were measured, which showed while addition of anions or metal ions Mg²⁺, Zn²⁺, Ca²⁺, Cu²⁺, Ni²⁺, Co²⁺, Fe³⁺ or Al³⁺ led to decrease in intensity of the maximum emission peak at about 480 nm, addition of Hg²⁺ ions caused increase in intensity of the maximum emission peak, suggesting that L may act as a fluorescent probe for detection of Hg²⁺ ions.
