摘要:

β-环糊精是由7个D-吡喃葡萄糖单元通过α-1,4-糖苷键键连成环的超分子主体分子,“内疏水、外亲水”的独特结构赋予了其优异的分子识别能力;氧化石墨烯类材料凭借其优良特性成为近几年的研究热点。由β-环糊精和氧化石墨烯构筑的超分子杂化体在兼具二者特有性能的基础上又有新功能的引入。本文综述了β-环糊精-氧化石墨烯超分子杂化体的构筑方式,按二者间的连接方式,分别为共价键和非共价键两种连接方式,其中通过共价键连接是目前最主要的构筑方式;此外对β-环糊精-氧化石墨烯超分子杂化体的特征和表征进行了简述。同时对β-环糊精-氧化石墨烯超分子杂化体在水污染处理、电化学检测、药物控释和催化等领域的应用进展进行了综述。最后对该超分子杂化体在构筑和应用上的发展趋势进行了展望。

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.

Key words: β-cyclodextrin, graphene oxide, supramolecular hybrid, molecular recognition, water pollution treatment, electrochemistry, pharmaceuticals, catalysis
