Fluorescence sensing is a simple, intuitive, and convenient detection method, but it also has disadvantages, such as poor photothermal stability and detection state limitations. Lanthanide organic/inorganic hybrid materials (LHMs) possess exceptional structural stability and tunability and are important candidates for chemosensory materials. LHMs contain versatile chemical reaction building blocks (linkers or ligands), and the different inorganic matrices that can be used provide an opportunity to develop and extend their unique properties.In this review, recent research progress on the use of LHMs for chemical sensing is described. We summarize four general strategies for LHMs synthesis. Moreover, by utilizing these strategies, we prepared an LHMs fluorescent probe that was used to realize the chemical sensing of different types of cations (Fe3+ and Cu2+), molecules (dipicolinic acid (DPA), glutathione, water and ascorbic acid (AA)), and pollutants (organic solvents and amines), as well as pH and temperature sensing. Additionally, the detection status of LHMs can be changed according to the characteristics of the inorganic matrix, such as whether a film or gel is used for detection, thereby overcoming the limitations related to the general detection state.

镧系有机/无机杂化系统:用于荧光检测的高效传感器

荧光传感是一种简单,直观,方便的检测方法,但它也有缺点,例如光热稳定性差和检测状态受限。镧系有机/无机杂化材料(LHM)具有出色的结构稳定性和可调性,是化学传感材料的重要候选材料。LHM包含通用的化学反应构建基块(连接基或配体),可以使用的不同无机基质为开发和扩展其独特特性提供了机会。在本综述中,描述了将LHM用于化学传感的最新研究进展。 。我们总结了LHMs合成的四种一般策略。此外,通过利用这些策略,我们制备了LHMs荧光探针,用于实现对不同类型阳离子(Fe3+和Cu 2+),分子(二吡啶甲酸(DPA),谷胱甘肽,水和抗坏血酸(AA))和污染物(有机溶剂和胺),以及pH和温度感应。另外,LHM的检测状态可以根据无机基质的特性而改变,例如使用膜还是凝胶进行检测,从而克服了与一般检测状态有关的限制。
