摘要：

The fluorescent probe has become an important method for the detection of heavy metal ions. In the present work, a new and simple fluorescent probe, Cu-P, for detecting copper ion (Cu2+) was designed and synthesized. The probe has shown high sensitivity and selectivity toward Cu2+. The detection limit was 13 nM (based on the 3 sigma/slope). A significant color change from yellow to pink was observed; thus, the probe Cu-P could serve as a "naked-eye" indicator for Cu2+. Furthermore, the proposed probe was used to detect Cu2+ in real water and soil extract samples, with the result being satisfactory. Therefore, our proposed probe would provide a promising method for the detection of Cu2+ in the environment.
