A team of Foundry staff and users developed a new synthetic strategy for making Covalent Organic Frameworks (COFs) with irreversible linkages and produced COFs with intrinsic proton conductivity.
Significance and Impact
This is the first time that COFs have been made with irreversible indazole and benzimidazolyidene linkages. It offers versatile options to construct COFs and control their functionality and opens the door to a broader class of functional porous materials.
- The team used a new approach combining imine chemistry with the Cadogan reaction to synthesize COFs with irreversible indazole- and benzimidazolyidene-linkages
- The BIY-COF displays excellent intrinsic proton conductivity without the need for external proton transfer reagents.
- The method offers versatile options to construct COFs with conceivable opportunities to control band gap and other semiconducting properties.
