| 摘 要： | 本文合成了一种具有吡咯酰胺和脲杂双识别位点的阴离子受体。利用紫外光谱法研究了该受体在乙腈溶液中对阴离子的识别作用。结果表明，该受体的识别能力比具有两个相同识别位点的受体的阴离子识别能力有所提高。同时，当仅当添加氟离子时，受体溶液的颜色会从无色变为黄色。表明，受体在氟离子的选择比色传感方面具有潜在的应用能力。

| Abstract: | A heteroditopic anion receptor, bearing one pyrrolic amide site and a urea site, has been synthesized. UV‐Vis spectrum studies in CH3CN solution revealed that the receptor had higher anion binding ability than the homoditopic one. A naked‐eye detectable color change, from colorless to yellow, of the receptor solution took place when fluoride was added, which indicates that the receptor has potential application to selective colorimetric fluoride sensing. |
