Fluorinated porous organic cages - Syntheses, Properties and Functionalization

该项目旨在开发前所未有的多孔氟化有机笼。 除了金属有机框架（MOFs）和共价有机框架（COFs）之外，多孔有机笼（POC）的特征在于模块化合成和优异的性能，例如热稳定性、催化活性、高气体亲和力和选择性。超疏水氟化MOFs的报道，并显示出有前途的气体吸附能力和水解稳定性。然而，氟化POC几乎不存在。我们的目标是合成氟化POC，研究它们的形成，超分子化学，材料性能，并将它们与已经报道的类似的非氟化POC进行比较。其次，我们开发了一种通用的反应后官能化“锁定”氟化POC。这为我们控制POC的内在和外在孔提供了可能。通过选择不同的异（硫）氰酸酯，一个或多个不同的官能团（或分子）可以共价连接到POC。

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.
