Deep Eutectic Solvents as media for the preparation of catalytically active Covalent Organic Frameworks – DEEPCatCOF

Submission summary

Associating three research groups with complementary expertise, the DEEPCatCOF project addresses two underexplored green aspects of porous materials of covalent-organic frameworks (COFs) type: i) the use of an emerging class of green media, deep eutectic solvents (DES) – cousins of ionic liquids – for the synthesis of COFs, and ii) the controlled installation on the backbone or in the nanopores of these tailor-made crystalline architectures of molecular catalysts based on the highly versatile first-row transition metal, nickel, as an alternative to rare metals, to afford novel heterogeneous catalysts for alkene hydrosilylations as a first development, then ambitious nickel/photoredox Csp2–Csp3or C–O cross-couplings, and ultimately challenging Murahashi-Feringa cross-couplings of organolithium compounds. Thus, the use of DES for the preparation of COFs will be explored to take advantage of the ability of these media to allow synthesis in open vessel, at lower temperature and/or in shorter reaction times compared to the classical solvothermal conditions. The obtained porous materials will be thoroughly characterized by an adequate panel of analytical techniques to assess their crystallinity and porosity and will then be employed for nickel complexation. The resulting Ni-COF materials will be analysed and studied for the targeted applications in heterogeneous (photo)catalysis.
