Background technique

Covalent organic frameworks (COFs) are a class of materials that form 2D or 3D structures through reactions between organic precursors, resulting in strong covalent bonds that provide porous, stable, and crystalline materials. COFs emerge as a field in the general field of organic materials as researchers optimize synthetic control and precursor selection. These improvements in coordination chemistry enable nonporous and amorphous organic materials such as organic polymers to enter the conformation of porous crystalline materials with rigid structures, providing excellent material stability under various solvents and conditions.
