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 x 10(-7)-6.0 x 10(-6) M with a detection limit of 1.7 x 10(-7) M Mg2+ in ethanol-water solution (9:1, v/v, 20 mM HEPES, pH = 10.0).
