离子型共价有机框架(iCOFs)是一种在框架或孔隙中存在离子基团且具有有序多孔结构的新型COF材料,这类材料不仅继承了传统COFs高比表面积、高结晶度、长程有序的孔径结构,而且由于其结构中的离子基团可以作为结合位点,使这类COFs在气体吸附与分离、离子传导、生物医药领域表现出独特的优势。通过介绍iCOFs的制备方法和不同离子基团的引入,综述了不同iCOFs在不同领域的研究进展和发展状况,对离子型COFs的制备手段进行了深入探讨,并对今后离子型COFs在相关领域的发展前景做出展望。
Ionic Covalent Organic Frameworks (iCOFs) are a new type of COF materials with ionic groups existing in the framework or pores and an ordered porous structure.This type of material not only inherits the high specific surface area,high crystallinity and long-range ordered pore structure of traditional COFs,but also shows unique advantages in the fields of gas adsorption and separation,ion conduction and biomedicine due to the ionic groups in its structure serving as binding sites.It reviewed the research progress and development status of different iCOFs in different fields by introducing the preparation methods of iCOFs and the introduction of different ionic groups,conducted an in-depth discussion on the preparation methods of ionic COFs,and looked forward to the development prospects of ionic COFs in related fields in the future.
