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 (Cu) was designed and synthesized. The probe has shown high sensitivity and selectivity toward Cu. The detection limit was 13 nM (based on the 3σ/slope). A significant color change from yellow to pink was observed; thus, the probe Cu-P could serve as a "naked-eye" indicator for Cu. Furthermore, the proposed probe was used to detect Cu 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 Cu in the environment.
荧光探针已成为检测重金属离子的重要方法。在本工作中，设计并合成了一种新型且简单的用于检测铜离子（Cu）的荧光探针Cu-P。该探针对Cu表现出高灵敏度和选择性。检测限为13 nM（基于3σ/斜率）。观察到明显的颜色变化，从黄色变为粉红色；因此，探针Cu-P可作为Cu的“肉眼”指示剂。此外，所提出的探针用于检测实际水样和土壤提取物样品中的Cu，结果令人满意。因此，我们提出的探针将为环境中Cu的检测提供一种有前景的方法。
