摘要
Covalent organic frameworks(CO Fs),as a type of promising crystalline porous materials produced from covalently linking of organic building units,have drawn considerable attention over the past decade.The light element composition and functional ordered frame structures of COFs lead to remarkable properties,such as low densities,exceptional stability,high surface areas,readily adjustable pore size and chemical environment,which make for applications of COFs including gas uptake and separation,catalysis,sensing,optoelectronics and proton conductivity.Herein,this themed column focuses on the burgeoning research of COFs involving the design,synthesis,characterization and applications of COF materials.
