Abstract Core–shell structures, where the “guest” material is encapsulated within a protective shell, integrate advantages of different materials to enhance overall properties composite. Covalent–organic frameworks (COFs) are favorable candidates for composing core–shell structures due their inherent porosity, good activity, excellent stability, and other advantages. In particular, COFs as shells encapsulate functional becoming increasingly popular in fields environmental remediation energy...
