Covalent Organic Frameworks

The development of methods for the preparation of covalent organic frameworks (COFs) represents a unique strategy in order to access porous 2D and 3D polymer networks. In comparison with other porous crystalline materials, COFs offer a singular combination of properties that make them unique materials and that include modularity, crystallinity, pososity, stability and low density. COFs have already found applications in the storage and separation of gases, in storage and separation from solutions, in catalysis, in electrochemical energy storage, in electrical devices, in optoelectronics, in sensing or in drug delivery among others. Functionality that cannot be introduced into COFs directly via de novo syntheses can be accessed through post-synthesis modification (PSM) strategies. In our group we are currently engaged (i) with the production of new COFs via de novo syntheses  and (ii) with the  post-synthetic modification of COFs with the aim to obtain novel materials for the fabrication of batteries, for nucleobase recognition, for the cleavage of nerve agent simulants and for water remediation among others.
