Sun Light Responsive 2D Covalent ‐Organic Frameworks Platform as a Catalysts Boost C–H Bond Arylation and Dopamine Regeneration

Here, we synthesized a sunlight-responsive 2D covalent-organic frameworks platform for boosting up C –H bond arylation and dopamine regeneration. 2D covalent-organic frameworks have been more effective due to their excellent band gap, photo-stability reusability and efficient electron transfer capability. The products with a C–H bond aryl group and generation of leucodopaminechrome have numerou s pharmaceutical uses. AbstractPhotocatalysis is one of the most promising methods for producing organic compounds with a renewable source of energy. Two-dimensional covalent organic frameworks (2D COFs) are a type of polymer that has developed as a potential light-harvesting catalyst for artificial photosynthesis with a design-controllable platform that might be developed into a new type of cost-effective and metal-free photocatalyst. Here, we present a two-dimensional covalent organic framework synthesis technique as a low-cost and highly efficient visible light active flexible photocatalyst for C –H bond activation and dopamine regeneration. 2D COF were synthesized from tetramino-benzoquinone (TABQ) and terapthaloyl chloride monomer through condensation polymerization reaction and the resultant photocatalyst have remarkable performance due to its visible light-harvesting capacity, appropri ate band gap, and highly organized π-electron channels. The synthesized photocatalyst is capable to convert dopamine into leucodopaminechrome with a higher yield (77.08%) and also capab...
