Naphthalimide has been widely used in probe research because of its unique structure. Therefore, using naphthalimide as matrix, a compound P was obtained by the reaction of pyridine-2-formaldehyde with naphthalimide derivative. Among the tested metal ions, the addition of Hg2+ to the solution of P in ethanol quenched the fluorescence of P at 525 nm, and a linear relationship between fluorescent intensity tothe concentration of Hg2+ in the range of 2.0×10-6-1.6×10-5 M was observed.
