Supramolecular fluorescent sensors have garnered extensive research attention and found broad applications in biochemical sensing attributed to their high selectivity, rapid response, stimulus responsiveness, and ease of modification, which stem from their inherent molecular recognition and self-assembly capabilities. Herein, supramolecular fluorescent sensors based on anthracene-functionalized naphthotubes have been successfully developed and utilized for the efficient detection of uranyl ions. Owing to the highly pre-organized carboxyl groups on the naphthotubes, uranyl ions are effectively captured, forming a non-fluorescent or weakly fluorescent complex to quench the fluorescence of anthracene. The fluorescent sensor exhibited a limit of detection as low as 53 nM, coupled with high sensitivity, rapid response time, and high selectivity. Moreover, it maintained robust detection capabilities in diverse aqueous environments such as seawater, river water, and tap water, demonstrating its promising potential for uranyl ions detection. This study provides a new idea for the development of detection methods for uranyl ions in complex environmental samples.
超分子荧光传感器因其具有高选择性、快速响应、刺激响应性和易于修饰等特点，源于其固有的分子识别和自组装能力，在生化传感领域引起了广泛的研究关注并得到了广泛应用。在此，基于蒽功能化萘管的超分子荧光传感器已成功开发并用于高效检测铀酰离子。由于萘管上高度预组织的羧基，铀酰离子被有效捕获，形成非荧光或弱荧光络合物以猝灭蒽的荧光。该荧光传感器的检测限低至53 nM，具有高灵敏度、快速响应时间和高选择性。此外，它在海水、河水和自来水等多种水环境中保持强大的检测能力，展示了其在铀酰离子检测方面的广阔前景。本研究为复杂环境样品中铀酰离子检测方法的开发提供了新思路。
