摘要
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。
The unique physicochemical properties of magnetic ionic liquid （MIL） have attracted increasing interest due to their potential applications in various areas. In this paper, recent progress in applications of magnetic ionic liquid has been reviewed and discussed. Magnetic ionic liquid is a kind of ionic liquid which formed by organic cation and inorganic anion. It can be absorbed on the magnet, and has a certain magnetization in the presence of external magnetic field. Magnetic ionic liquid is a green solvent. In addition, magnetic ionic liquid can play as solvent, catalyst and template in organic synthesis, the resulting product is easy to separate and the structure of the product can be adjusted by an external magnetic field. Magnetic ionic liquid can be recycled and reused, and the catalytic activity of magnetic ionic liquid is not significantly reduced. In areas of separation, analysis, preparation of nano-materials, magnetic ionic liquid also have unique advantages. Especially, magnetic carbon nanotubes can be synthesized by using magnetic ionic liquid and carbon nanotubes.
