Development and Applications of Covalent Organic Frameworks(COFs) Materials: Gas Storage, Catalysis and Chemical Sensing

Covalent organic frameworks (COFs) are porous compounds with periodic topology structures in which the organic building units are linked by covalent bonds. As a new type of crystalline porous organic materials with multiple advantages, such as low density, large surface area, porosity, good crystallinity, high stability, designable structural units and so on, they have won more and more attention of scientists and been widely applied in many fields including gas adsorption and separation, optoelectronic device, catalysis, drug delivery, energy storage, chemical sensing and chromatographic separation. In the present paper, development and application advances of COFs materials are reviewed in outline, the burning issues concerning the applications are summarized and their possible development trends are also prospected.
