While significant progress in covalent organic frameworks (COFs) has been made in recent years, the construction of COFs with heterogeneous porosity remains a great challenge. In this communication, we report two novel 2D heteropore COFs which bear two kinds of hexagonal micropores with different shapes and sizes. They have been constructed by the condensation of monomers with C_2v- and D_3h-symmetry, and their structures have been confirmed by PXRD studies, synchrotron SAXS experiments, theoretical simulations and pore size distribution analyses.

基于C _2v和D _3h对称构件的组合构建二维异孔共价有机骨架的设计策略†

尽管近年来共价有机骨架（COF）取得了重大进展，但具有非均质孔隙率的COF的构建仍然是一个巨大的挑战。在本次交流中，我们报告了两种新颖的二维异型孔COF，它们带有两种形状和大小不同的六边形微孔。他们已经用单体的冷凝构建Ç _2V -和d _3H -symmetry，其结构已被PXRD研究证实，同步SAXS实验，理论模拟和孔径分布分析。
