由于无序连接方式的存在，有效地控制多孔有机聚合物(POPS)的孔径仍然是一个巨大的挑战。在这里，我们利用有机分子笼(OMC)，具有固定的本征空穴、大量的反应中心和可溶解的加工特性，通过共价交叉偶联反应构建了高价的分子笼基POMC(TPP-POMC)。在形成的TPP-POMC中，TPP-OMC的起始封闭孔道被“开启”，形成与笼内连接的固有空腔相对应的固定孔道(5.3？)，以及笼与笼之间的分子间孔道(1.34和2.72 nm)。因此，TPP-POMC的Brunauer-Emmett-Teller(BET)比表面积和CO2吸附容量显著提高。通过利用笼到骨架的策略，打开笼本身的封闭孔，构建了基于高共价分子笼的多孔有机聚合物。
It remains a great challenge to effectively control the pore size in porous organic polymers (POPs) because of the disordered linking modes. Herein, we used organic molecular cages (OMCs), possessing the properties of fixed intrinsic cavities, high numbers of reactive sites and dissolvable processability, as building blocks to construct a molecular cage-based POP (TPP-pOMC) with high valency through covalent cross coupling reaction. In the formed TPP-pOMC, the originating blocking pore channels of TPP-OMC were “turned on” and formed fixed pore channels (5.3 Å) corresponding to the connective intrinsic cavities of cages, and intermolecular pore channels (1.34 and 2.72 nm) between cages. Therefore, TPP-pOMC showed significant enhancement in Brunauer–Emmett–Teller (BET) surface area and CO2 adsorption capacity. By utilizing the cage to framework strategy, the blocking pores of the cage itself were “turned on” to construct a highly covalent molecular cage based porous organic polymer.
