Research Progress in Donor−Acceptor Type Covalent Organic Frameworks

Research Progress in Donor−Acceptor Type Covalent Organic Frameworks Covalent organic frameworks (COFs) are new organic porous materials constructed by covalent bonds, with the advantages of pre-designable topology, adjustable pore size, and abundant active sites. Many research studies have shown that COFs exhibit great potential in gas adsorption, molecular separation, catalysis, drug delivery, energy storage, etc. However, the electrons and holes of intrinsic COF are prone to compounding in t...
