Research Progress of Fluorescence Probes Constructed by Cyclodextrin Derivatives and Inclusion Complexes

Cyclodextrins are a kind of the most important host compounds in supramolecular chemistry, and have been widely used in many fields such as drug release, chemical sensing, enantiomer separation and new materials.Because cyclodextrins have a barrel-shaped structure that is hydrophilic on the outside and hydrophobic on the inside, receptors with recognition functions or fluorescent dyes can be inserted into the cavity of cyclodextrins, which can realize the recognition of target molecules by chelation or displacement.Therefore, construction of fluorescent probes based on cyclodextrins derivatives and inclusion complexes has been received great attention.In this paper, the applications of fluorescent probes that designed and synthesized based on cyclodextrins in the detection of metal ions, anions and molecules are summarized, the recognition performance and mechanisms are described, and it is expected to provide theoretical basis for the application of cyclodextrin derivatives and inclusion complexes in the field of fluorescence detection.
