Porous materials are widely used in energy, environment and other national strategic fields, which play an important role in the development of national economy, the development of new porous materials is of great significance. Our laboratory specia-lizes in 3D COF (a unique class of crystalline porous materials that allow the precise integration of organic molecular building blocks into 3D networks through covalent bonds), including design and synthesis, as well as exploring the applications of 3D COF in the fields of adsorption and separation, optoelectronics, catalysis, and energy storage, and beyond.
