Covalent organic frameworks (COFs) are two-dimensional or three-dimensional crystalline porous polymer materials formed by organic structural units connected by covalent bonds. They have high thermal stability, large specific surface area, abundant pores, and tunable molecular structure and multiple features active sites. Unlike metal-organic frameworks (MOFs), COFs can be composed entirely of light elements such as carbon, hydrogen, nitrogen, and oxygen, without heavier elements such as metals. The building blocks of COFs must contain reactive groups that can initiate reversible reactions while maintaining the structure. The building block can support the material skeleton, restrict the free rotation of the polymer chain, avoid the deformation or collapse of the skeleton structure, and provide more free voids. Therefore, the size of the building block can be controlled by changing the size of the building block and adjusting the length of its side chain to control the size of the material pore size. At present, hundreds of COFs of different dimensions have been synthesized through the same building unit, including various bond types such as C=N, B-N, B-O-B, B-O-C, and B-O-Si. Among them, the synthesis of COFs by acetonitrile COFs linkers is a kind of C=N bond type, and it involved in the formation include imide-based COFs, vinylidene covalent organic frameworks, and triazine-based COFs.
