Covalent organic frameworks (COFs) are an emerging class of porous crystalline organic materials connected by covalent bonds. Owing to their high crystallinity, low density, large surface area and designable structures, COFs have potential applications in molecular adsorption and separation, catalysis, optoelectronic devices, and energy storage. Recently, due to their inherent characteristics, COFs have attracted a lot of interests in sensing. The research progress of COFs in sensing, including explosive sensing, humidity sensing, metal ions sensing, pH sensing, biosensing and gas sensing is summarized. Finally, a perspective of the application of COFs in sensing is given.
Key words: covalent organic frameworks, sensing, explosive, metal ion, gas molecule
