2D covalent organic frameworks (COFs) are a class of porous polymers with highly crystalline structures and tunable function. The structure of a 2D-COF consists of two dimensional sheets held together through covalent bonds which are then stacked together through non-covalent forces. Since their first report, the synthesis of new COFs has relied mostly on imparting functionality to the monomer structures through covalent modification, or through the use of new thermodynamically controlled covalent bond forming methods. This tutorial review will discuss recent efforts to use supramolecular design to leverage the non-covalent forces between COF monomers and sheets to improve their properties and function. The importance of supramolecular interactions in COFs to their mechanisms of formation and overall structure will also be covered.
二维共价有机框架（COFs）是一类具有高度结晶结构和可调节功能的多孔聚合物。二维COF的结构由通过共价键连接在一起的二维薄片组成，这些薄片再通过非共价力堆叠在一起。自首次报道以来，新型COF的合成主要依赖于通过共价修饰赋予单体结构功能，或者使用新的热力学控制的共价键形成方法。本教程综述将讨论最近利用超分子设计来利用COF单体和薄片之间的非共价力以改善其性质和功能的努力。还将涵盖超分子相互作用在COFs中对其形成机制和整体结构的重要性。
