COFs

Covalent organic frameworks (COFs) are a promising new type of porous crystalline material, which is constructed with organic units via strong covalent bond. Unlike MOFs which contain metal elements in their structures, COFs are composed of light-weight elements, therefore that their mass density is low in regards to other kinds of porous materials. In addition, COFs also possess high thermal stability, and permanent porosity so they are excellent for many applications, such as gas storage, conductivity, and catalysis.
