共价有机骨架材料设计及其在分离领域的应用

Progress in the Syntheses of Covalent Organic Frameworks and Their Applications in Separation

共价有机骨架(COFs)材料是由有机小分子单体通过共价键连接形成的结晶多孔聚合物。与传统的线性聚合物不同的是,COFs可以在二维和三维空间上对其骨架结构进行控制,从而合成具有高度有序的刚性多孔结构,并且能够调节骨架的化学和物理性质。这种由COF形成的纳米级孔道和空间为分子存储、释放和分离提供了理想的环境。因此它在能量储存、分离、催化等领域有着广泛的应用前景。本文综述了近年来COFs材料的研究进展,主要包括材料的合成策略及其在分离领域的应用,并对COFs材料未来的发展方向进行了展望。

Covalent organic frameworks(COFs)are crystalline porous polymers formed by covalent bonding of small organic molecules.Unlike typical linear polymers,COFs offer fine control over their skeletons in two and three dimensions,which enables the synthesis of rigid porous structures with high regularity and tunable chemical and physical properties.The nanoscale channels and voids in COFs provide an ideal environment for molecular storage,release and separation,endowing them great potential in energy adsorption,separation,and catalysis.This article reviews the progress in COFs,including the synthesis strategies,the applications in separation field as well as outlook of their future developments.
