【 摘 要 】

A new Mg²⁺-selective fluorescent probe P was synthesized and characterized. With optimal conditions, the proposed probe P showed good selectivity to Mg²⁺ compared to other common metal ions, and worked in a wide linear range of 5.0 × 10⁻⁷–6.0 × 10⁻⁶ M with a detection limit of 1.7 × 10⁻⁷ M Mg²⁺ in ethanol-water solution (9:1, v/v, 20 mM HEPES, pH = 10.0).
