多孔有机笼（POC）代表了一类新的微孔材料，具有令人印象深刻的潜在应用范围。它们的许多优点之一是笼特性的可调性，类似于在更成熟的微孔材料如金属有机框架中看到的。在这项工作中，使用原型POC CC3来探索通过合成后动态共价化学调节笼特性的潜力。基于起始相对摩尔比，乙二胺（用于另一种POC CC1中的连接基）部分取代到CC3笼状结构中至不同程度。研究了所得产物的两种连接剂的相对分布、结晶度和表面积。有人发现，即使当少量的其他相容的二胺连接器被引入，它们取代到现有的笼，虽然一些结构的产品显然是优于其他的反应物比例内调查。
Porous organic cages (POCs) represent a new class of microporous materials with an impressive breadth of potential applications. One of their many advantages is the degree of tunability of cage properties, similar to that seen in more established microporous materials like metal‐organic frameworks. In this work, a prototypical POC, CC3, is used to explore the potential to tune cage properties via post‐synthetic dynamic covalent chemistry. Ethylenediamine, the linker used in another POC, CC1, was partially substituted into the CC3 cage structure to varying degrees based on the starting relative molar ratios. The resulting products were investigated for the relative distribution of the two linkers, crystallinity, and surface area. It was found that even when small amounts of other compatible diamine linkers are introduced, they substitute into the existing cages, although some structural products are apparently favored over others within the reactant ratios investigated.
