The marriage of dynamic covalent chemistry (DCC) and coordination chemistry is a powerful tool for assembling complex architectures from simple building units. Recently, the synthesis of woven covalent organic frameworks (COFs) with topologically fascinating structures has been achieved using this approach. However, the scope is highly limited and there is a need to discover new pathways that can assemble covalently linked organic threads into crystalline frameworks. Herein, we have identified branching pathways leading to the assembly of three-dimensional (3D) woven COFs or one-dimensional (1D) metallo-COFs (mCOFs), where the mechanism is underpinned by the absence or presence of ligand exchange.
动态共价化学（DCC）与配位化学相结合，是一种利用简单构建单元组装复杂结构的强大工具。最近，通过这种方法已经实现了具有拓扑结构迷人的编织共价有机框架（COF）的合成。然而，其应用范围非常有限，需要探索新的途径，将共价连接的有机链组装成晶体框架。在此，我们确定了导致三维（3D）编织COF或一维（1D）金属有机框架（mCOF）组装的分支途径，其机制取决于配体交换的有无。
