摘要
本文介绍了小分子荧光探针以及超分子荧光探针在甲醛识别中的应用,总结了小分子荧光探针与甲醛发生作用的反应类型,特别关注了超分子荧光探针的研究进展。甲醛作为一种环境中常见的有毒挥发性有机化合物,对人体健康构成严重威胁,因此开发简单、灵敏且高选择性的检测方法显得尤为重要。有机荧光探针以其设备需求简单、操作便捷、响应迅速,高灵敏度,可在线实时检测等优势,为甲醛检测提供可靠便捷的工具。其中小分子荧光探针主要通过与甲醛发生化学反应引起荧光变化,与之相比,超分子荧光探针由于同时具有限域空腔和与甲醛分子的结合活性位点,因此展现出更高的灵敏度、更快的响应速度和更好的选择性。最后,本文指出了超分子荧光探针在生物医学和环境监测等领域的广阔应用前景,并对其未来的发展方向进行了展望。
In this paper,the application of small molecule fluorescence probes and supramolecular fluorescence probes in formaldehyde recognition was introduced,and the types of reaction between small molecule fluorescence probes and formaldehyde were summarized.In particular,the research progress of supramolecular fluorescence probes was paid special attention.As a common toxic volatile organic compound in the environment,formaldehyde poses a serious threat to human health,so it is particularly important to develop simple,sensitive and highly selective detection methods.Organic fluorescence probe provides a reliable and convenient tool for formaldehyde detection with its advantages of simple equipment requirements,convenient operation,rapid response,high sensitivity and on-line real-time detection.Among them,small molecule fluorescence probes mainly cause fluorescence changes through chemical reactions with formaldehyde.Compared with supramolecular fluorescence probes,they show higher sensitivity,faster response speed and better selectivity because they have both a limited cavity and a binding active site with formaldehyde molecules.Finally,the broad application prospect of supramolecular fluorescence probes in biomedicine and environmental monitoring is pointed out,and the future development direction of the probes is forecasted.
