Abstract:

β-Cyclodextrin is a supramolecular host molecule in which seven D-glucopyranose units are bonded to each other via an α-1,4-glycosidic bond and has an excellent molecular recognition ability because of its unique structure of hydrophilic external cavity and hydrophobic internal cavity. Graphene oxide-based materials are a research hotspot in recent years due to their excellent properties. The supramolecular hybrid consisted of β-cyclodextrin and graphene oxide has the unique properties of the two and the new functions. The preparation method of β-cyclodextrin-graphene oxide supramolecular hybrid was reviewed. There were two kinds of connection methods with the covalent bond and non-covalent bond according to the connection mode, of which the covalent bond connection was the important method to prepare the β-cyclodextrin-graphene oxide supramolecular hybrid for the present. The characteristics and characterization of β-cyclodextrin-graphene oxide supramolecular hybrid were briefly described. Meanwhile, the applications of β-cyclodextrin-graphene oxide supramolecular hybrid in water pollution treatment, electrochemical detection, pharmaceuticals controlled release and catalysis were reviewed, respectively. Finally, the development directions of this supramolecular hybrid in preparation and application were prospected.
