Linkage engineering of covalent-organic frameworks for CO2 capture

The growing concern over climate change due to the continuous increase in CO2 concentration calls for efficient ways for carbon capture. Covalent-organic frameworks (COFs), as a new type of porous materials, are considered ideal platforms for carbon capture due to their high surface area and porosity, while their intrinsic CO2 uptake is relatively low owing to the lack of functionalities. Herein, we report a linkage engineering strategy to …
