摘要
详细综述了目前β-环糊精-Fe3O4超分子体系的构筑及其应用进展,主要包括以共价键键连的β-环糊精-Fe3O4超分子体系在环境污染物吸附、药物分子负载和缓释、传感检测、分离和催化领域中的应用.上述各部分中,根据β-环糊精与Fe3O4纳米粒子之间连接基团的不同,对各类β-环糊精-Fe3O4超分子体系的构筑及其性能进行了系统介绍.指出β-环糊精-Fe3O4超分子体系兼具β-环糊精的包结吸附性能、弱催化性能及底物识别性能和Fe3O4组分的磁性载体作用,易于回收;β-环糊精固载在Fe3O4纳米粒子上,构筑非均相β-环糊精-Fe3O4超分子仿生催化体系,是今后构筑纳米级超分子仿生催化剂的研究热点之一.
The construction and application of β-cyclodextrin-Fe3O4 supramolecular systems at present have been reviewed in detail, especially for the application of β-cyclodextrin-Fe3O4 supramolecular systems constructed covalently in the environ- mental pollutants adsorption, drug loading and releasing, sensor construction and detection application, separation and catal β- sis. In all of the section mentioned above, the construction and property of the β-cyclodextrin-Fe3O4 supramolecular systems were discussed systematically which were classified according to the linking groups between fl-cyclodextrin and Fe3O4. It was pointed out that the β-cyclodextrin-Fe3O4 supramolecular systems possessed the ability to form inclusion complex with guest molecules, weak catalytic activity and substrate recognition property of β-cyclodextrin unit and the magnetic property of Fe3O4 which could be recovered easily, simultaneously. It was also pointed out that the immobilization of β-cyclodextrin on Fe3O4 nanoparticles to construct heterogeneous β-cyclodextrin-Fe3O4 supramolecular biomimetic catalytic systems will be one of the focus in the construction of nanoscale supramolecular biomimetic catalysts in the future.
