The project aims to develop unprecedented porous fluorinated organic cages. Alongside metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), porous organic cages (POCs) are characterised by a modular synthesis and excellent properties such as thermal stability, catalytic activity, high gas affinity and selectivity. Ultra-hydrophobic fluorinated MOFs were reported and show promising gas adsorption capabilities and hydrolytic stability. However, fluorinated POCs are almost non-existent. We aim to synthesize fluorinated POCs to study their formation, supramolecular chemistry, material properties and compare them to similar non-fluorinated POCs, that were already reported. Second, we developed a general reaction to postfunctionalize “locked” fluorinated POCs. This gives us the possibly to control the intrinsic as well as extrinsic pore of the POC. By choosing different iso(thio)cyanates, one or more different functional groups (or molecules) can covalently be attached to the POC.

该项目旨在开发前所未有的多孔氟化有机笼。除了金属有机骨架（MOFs）和共价有机骨架（COFs）外，多孔有机笼（POCs）的特点是模块化合成和优异的性能，如热稳定性、催化活性、高气体亲和性和选择性。超疏水氟化mof具有良好的气体吸附性能和水解稳定性。然而，氟化POCs几乎不存在。我们的目的是合成氟化POCs，研究其形成、超分子化学、材料性质，并将其与已报道的类似的非氟化POCs进行比较。其次，我们对后功能化“锁定”氟化POCs进行了一般反应。这使我们有可能控制POC的内在和外在孔隙。通过选择不同的异（硫）氰酸盐，一个或多个不同的官能团（或分子）可以共价地附着在POC上。
