WebHowever, the linker exchange method has so far only been described for COFs with relatively weak linkages, like imines. Herein it is shown that this method can be also used for a post-synthetic linker exchange reaction on a ß-ketoenamine linked COF. The time needed to achieve considerable linker exchange is much prolonged compared to other ...

WebIn conclusion, we could demonstrate the successful integration of a terphenyldiboronic acid based linker and HHTP into a highly porous COF material via boronate ester formation. In addition, it was possible to incorporate small functional groups into the framework by integrating hydroxyl groups into the terphenyl-based COF linker. This linker ... WebCOF materials are synthesized by the covalent linkage of organic molecules bonded in a repeating fashion to form a porous crystal that is ideal for gas adsorption and storage. Chemists have strategically designed COFs for the purpose of heterogeneous catalysis of gaseous reactants.
