Three-dimensional (3D) covalent organic frameworks (COFs) are excellent crystalline porous polymers for numerous potential appli-cations, but their building units and topological nets have been lim-ited. Herein we report the design and synthesis of the first 3D large-pore COF with stp topology constructed from a 6-connected triptycene-based monomer. The new COF (termed JUC-564) has a high specific surface area (up to 3300 m2 g-1), the largest pore (43 Å) among 3D COFs, and record-breaking low density (0.108 g cm-3) in crystalline materials to date. The large pore size of JUC-564 is confirmed by the incorporation of a protein. This study expands the structural varieties of 3D COFs based on the deliberate symmetry-guided design principle as well as their applications for adsorption and separation of large biological molecules.

具有 stp 拓扑结构的三维大孔共价有机骨架
三维 (3D) 共价有机骨架 (COF) 是用于众多潜在应用的优异结晶多孔聚合物,但它们的构建单元和拓扑网络受到限制。在此,我们报告了第一个 3D 大孔 COF 的设计和合成,其 stp 拓扑结构由基于 6 连接的三苯乙烯基单体构成。新的 COF(称为 JUC-564)具有高比表面积(高达 3300 m2 g-1)、3D COF 中最大的孔隙(43 Å)和创纪录的低密度(0.108 g cm-3)迄今为止的结晶材料。JUC-564 的大孔径通过蛋白质的掺入得到证实。本研究基于有意的对称引导设计原则扩展了 3D COF 的结构种类及其在大生物分子的吸附和分离方面的应用。
