摘要

以芘甲醛为原料合成了一种新型探针P。在乙醇-水(乙醇:水=3.5:1.5,pH 6.5, 0.02 M HEPES)溶液中，探针对Cu2+的选择性优于其他金属离子。随着Cu2+浓度的增加(2 ~ 10 μM)， P-Cu2+体系在464 nm处呈现良好的线性关系，检出限降至0.66 μM。

Design of Highly Selective Cu2+ Fluorescent Probe Based on Pyrene Derivatives

A new probe P was synthesized and characterized from pyrene formaldehyde. The probe showed good selectivity for Cu2+ over other metal ions in ethanol-water solution (Vethanol:Vwater=3.5:1.5, pH 6.5, 0.02 M HEPES). With the increasing of Cu2+ concentration (2-10 μM), the P-Cu2+ system displayed excellent linear relationship at 464 nm with the detection limit down to 0.66 μM.
