Ester-linked, crystalline, porous, covalent organic frameworks (COFs) have been synthesized and structurally character-ized. Transesterification reactions between di-topic 2-pyridinyl aromatic carboxylates and tri- or tetra-topic phenols gave the corresponding ester-linked COFs. They crystallize as 2D structures in kgm (COF-119) and hcb (COF-120, 121, 122) topologies with surface areas of up to 2,092 m2/g. Notably, crystalline COF-122 comprises edges spanning over 10 phe-nylene units; an aspect had only been achieved in metal-organic frameworks. This work expands the scope of reticular chemistry to include for the first time crystalline ester-linked COFs, related to common polyesters.

酯键连接的结晶共价有机框架
酯连接的、结晶的、多孔的、共价有机骨架 (COF) 已被合成并在结构上进行了表征。双位 2-吡啶基芳族羧酸盐和三位或四位酚之间的酯交换反应得到相应的酯连接的 COF。它们以 kgm (COF-119) 和 hcb (COF-120, 121, 122) 拓扑结构结晶为二维结构，表面积高达 2,092 m2/g。值得注意的是，结晶 COF-122 包含跨越 10 个亚苯基单元的边缘；一个方面仅在金属有机框架中实现。这项工作扩展了网状化学的范围，首次包括与普通聚酯相关的结晶酯连接 COF。
