摘要：

A novel fluorescent probe L consisting of beta-Cyclodextrin (beta-CD) and thiosemicarbazide moieties was designed for copper ions detection. Apparent fluorescence quenching of probe L in Tris-HCl(pH = 7.4)solution was observed only in the presence of Cu2+, among other interfering ions. The present probe L was 1:1 complexed with Cu2+ and the detection limit of probe L was calculated to be 1.37 mu M. The results demonstrate that the probe L may provide a convenient method for visual detection of Cu2+ in the environmental and biological systems.
