基于8-羟基喹啉衍生物的金属离子荧光分子探针研究进展

In recent years, while metal ion fluorescent probes have the advantage of high sensitivity, instantaneous response, low detection limit, and convenient operation, a large amount of fluorescent probes have been developed for various metal ions. Compounds derived from 8-hydroxyquinoline have some excellent properties such as good metal coordinating ability, unique fluorescence properties and excellent biocompatibility, which are of great potential application value in the fluorescence detection of metal ions. Therefore, it is also of great potential application value in the detection of metal ions, biological fluorescence imaging and so on to design compounds based on 8-hydroxyquinoline derivatives. This review introduces and summaries the research progress of 8-hydroxyquinoline derivatives as metal ion fluorescent probes.
