What is the Difference Between MOF and COF

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. WebThe same phenomenon was observed by Teoh et al. following a different approach: supramolecular functionalization of a 2D-cyanovinylene-linked COF by a TEMPO derivative with pyrene units was performed, able to establish π–π interactions with the aromatic structure of the framework.
