Currently, the fluorescent probe is an important method for detecting heavy metal ions, especially mercury ion (Hg ), which is harmful to the health of humans and the environment due to its toxicity and extensive use. In this paper, we designed and synthesized a colorimetric and long-wavelength fluorescent probe Hg-P with high sensitivity and excellent selectivity, which could detect Hg by the changes of visual color, fluorescence and absorption spectroscopy. With the addition of Hg to probe Hg-P solution, its color changed from yellow to pink, and showed a 171 nm red-shifted absorption spectrum. Probe Hg-P was used in real water and soil solution samples to detect Hg , and the result is satisfactory. Therefore, this new probe shows great value and application in detecting Hg in the environment.
目前，荧光探针是检测重金属离子的重要方法，尤其是汞离子（Hg ），由于其毒性和广泛使用，对人类健康和环境有害。本文设计合成了一种具有高灵敏度和优异选择性的比色和长波长荧光探针Hg-P，该探针可通过视觉颜色、荧光和吸收光谱的变化来检测Hg 。向探针Hg-P溶液中加入Hg 后，其颜色由黄色变为粉红色，并呈现出171 nm的吸收光谱红移。将探针Hg-P用于实际水样和土壤溶液样品中检测Hg ，结果令人满意。因此，这种新型探针在环境中Hg 的检测方面具有很大的价值和应用前景。
