What are Covalent Organic Frameworks (COFs)?
Covalent organic frameworks
Covalent organic frameworks (COF’s) are a class of extended crystalline organic materials that possess unique properties with high surface areas and adjustable pore sizes. Since the first discovery of the topological frameworks in 2005, COFs have been applied as promising materials in diverse areas such as separation and purification, sensing or catalysis.
Since COF’s are based on carbon and hydrogen they have potential to be a more stable and sustainable class of materials replacing MOF’s that consist of a metal and ligands. MOF’s are widely used in applications like adsorption, membrane separation, sensing, catalysis, and proton conduction.
Making organic frameworks in the form of films is challenging and Carpona is striving to meet this challenge and facilitate research.
