摘　　要：小分子荧光探针应用于检测污染物具有高选择性、高灵敏度和可视化等优点,但其检测效率低,难以与本体分离回收,对环境有一定污染。通过化学方法将小分子荧光探针负载到介孔材料表面,可以克服小分子荧光探针的不足,实现小分子荧光探针和介孔材料的优势互补。基于介孔材料的荧光探针不但兼具了小分子荧光探针的识别及清除功能,还可以通过调整介孔材料孔径大小和孔材料的成分实现更低浓度的检测,提高检测的灵敏度。本文首先综述了近年来基于介孔材料的不同类型荧光探针的研究进展,重点阐述荧光探针修饰的介孔材料在重金属离子检测、有机小分子检测、生物分子检测和阴离子检测等方面的应用,最后对基于介孔材料的荧光探针发展方向进行了展望。Small molecular fluorescent probe possess such advantages as high selectivity,high sensitivity and visualization when applied in detecting the pollutants. However,the draw back of low detection efficiency,difficulty to separate and recovery from bulk solution and pollution to the environment can not be overcome.Small molecules fluorescent probes loaded on the surface of mesoporous materials by chemical methods can combine the advantages of fluorescent probes and mesoporous materials. The mesoporous material-based fluorescence probe can not only possess the function of detection and clearance of small molecular fluorescent probe,but also may achieve low er concentration detection and enhance the detection sensitivity by adjusting the pore size and components of mesoporous materials. This paper review s the research progress of different mesoporous materials-based fluorescent probes firstly. The applications of different mesoporous materials-based fluorescent probes in the detection of heavy metal ions,organic small molecules,biological molecules and anions are elucidated emphasizedly. Lastly,the future studies for mesoporous materials-based fluorescent probes are also expected.
