摘要：

A novel fluorescent compound derived from calixarene which possesses two 3-alkoxy-2-naphthoic acid moieties has been synthesized in moderate yield. In H2O/CH3OH (1:1), its fluorescent intensity was quenched sharply in the presence of Cu2+ or Fe3+, and the degree of quenching was related to the pH of the solution. Other metal ions, such as Co2+, Ni2+, Zn2+, Mn2+, Mg2+ and Ba2+ did not affect its fluorescent spectra. This research may provide a new fluorescent probe for Cu2+ and Fe3+.
