The synthesis and characterization of CCOFs

Abstract

Covalent organic frameworks (COFs) are a class of crystalline, porous organic polymers with highly ordered structures. They are composed mainly of light elements (H, B, C, N and O) connected by dynamic covalent bonds. The specificity of their physical and chemical properties: high crystallinity, customizable pore size and shape, large specific surface area, and high stability in a wide range of solvents make COFs unique among all types of porous organics. The synthesis of covalent organic frameworks is mainly classified into: solvothermal synthesis, microwave synthesis, ionothermal synthesis, and room temperature synthesis. Chiral covalent organic frameworks (CCOFs), which are materials constructed from organic structural units with enantiomeric purity and linker substituents and assembled by condensation reactions, are a subtype of COFs with well-defined crystal structures. During this experiment, Tp-based CCOFs materials were synthesized and characterized.
