磁性离子液体是指能够吸附在磁铁上,在外加磁场作用下具有一定磁化强度的离子液体。本文综述了自2004年磁性离子液体概念提出至今在各领域的应用,其可以催化吡咯、3-甲基噻吩等单体合成导电高分子纳米微球,同时起到溶剂和模板的作用;还可以通过外加磁场调整产物的微观结构和形貌,从而得到不同的纳米结构;它也可以充当Lewis酸催化剂,催化傅克反应等一系列化学反应,并可以回收重复使用,而且回收有望通过磁场简单实现;与碳纳米管以共价键结合可以制备具有磁性的碳纳米管。除此之外,磁性离子液体在光控顺磁性超分子体系、吸收有机挥发物等领域的应用在近年也陆续有报道。
Magnetic ionic liquid refers to be able to adsorb on the magnet, in the external magnetic field with a certain magnetization of ionic liquid. This review summarizes the applications of the concept of magnetic ionic liquids since 2004 in various fields so far. It can catalyze the synthesis of conductive polymer nanospheres from monomers such as pyrrole and 3-methylthiophene and also act as solvents and templates. By adjusting the microstructure and morphology of the product by external magnetic field, different nanostructures can be obtained; it can also act as a series of chemical reactions such as Lewis acid catalyst and catalytic Frieff reaction, which can be recycled and reused, and the recovery is expected to be realized simply by the magnetic field ; With carbon nanotubes covalent bond can be prepared with magnetic carbon nanotubes. In addition, the application of magnetic ionic liquids in the field of photo-controlled paramagnetic supramolecular systems and absorption of organic volatiles has also been reported in recent years.
