毛细管整体柱由于具备高效的传质性能、分离性能以及灵活的可设计性,受到科研工作者的广泛关注。整体柱制备过程中,功能基团的引入是关键点之一。近年来研究者们将一种简单高效、定向性强的反应-“巯-烯点击反应”引入整体柱的制备中,由于含巯基、含烯键的配体和单体具有非常广泛的可选择性,因而使整体柱材料更加多样化。本文从整体柱的特征、分类及制备方法出发,阐述了传统整体柱制备方法的局限性以及引入巯-烯点击反应的优势。并且分别从两个方面重点综述了“巯-烯点击反应”在整体柱制备中的应用:即利用巯-烯点击反应对表面含烯键或者巯基的整体柱进行表面修饰以及基于巯-烯点击反应“一锅法”制备的杂化整体柱。最后展望了巯-烯点击反应在整体柱制备领域的发展前景。
Capillary monolithic column due to the efficient mass transfer performance, separation performance and flexible design, by the researchers of concern. The overall column preparation process, the introduction of functional groups is one of the key points. In recent years, researchers have introduced a simple, efficient and highly directional reaction - “thio-ene click reaction” into the preparation of monoliths. Since sulfhydryl-containing and olefin-containing ligands and monomers have a very wide range of Optional, thus making the monolithic material more diverse. In this paper, the characteristics, classification and preparation methods of monolithic columns are introduced. The limitations of traditional monolithic column preparation methods and the advantages of the introduction of thiol-ene click reaction are described. In addition, the applications of “thio-ene click reaction” in monolithic column preparation are reviewed respectively from two aspects: the surface modification of the monolith with ethylenic or mercapto groups on the surface by mercapto-ene click reaction, Ene click reaction “one pot method ” prepared hybrid monolithic column. Finally, the prospect of the thio-ene click reaction in the field of monolithic column preparation is prospected.
