Hollow porous organic capsules (HPOCs) with an entrapped active catalyst have nanosized cavities, providing the benefits of a nanoreactor, as well as separation of the catalysts from the reaction medium via pores acting as a size-exclusion gate. Such purpose-built HPOCs with desired molecular weight cutoffs offer the advantages of semipermeable membrane separation and a sustainable chemical process that excludes energy-extensive separation. Here, we report a newly synthesized HPOC with an entrapped Pd(PPh₃)₂Cl₂ as the catalyst for demonstrating a Suzuki–Miyaura coupling reaction as a proof of concept.

中空有机笼状纳米胶囊中的微孔作为尺寸排阻门：笼状包埋的 Pd(II) 催化剂用于高效交叉偶联反应

含有活性催化剂的中空多孔有机胶囊 (HPOC) 具有纳米尺寸的空腔，具有纳米反应器的优点，以及通过充当尺寸排阻门的孔将催化剂与反应介质分离。这种具有所需截留分子量的专用 HPOC 具有半透膜分离和可持续化学工艺的优点，无需消耗大量能源的分离。在这里，我们报告了一种新合成的 HPOC，其具有包埋的 Pd(PPh ₃ ) ₂ Cl ₂作为催化剂，用于演示 Suzuki-Miyaura 偶联反应作为概念证明。
