Porous polymer explained

Porous polymers are a class of porous media materials in which monomers form 2D and 3D polymers containing angstrom- to nanometer-scale pores formed by the arrangement of the monomers. They may be either crystalline or amorphous. Subclasses include covalent organic frameworks (COFs), hydrogen-bonded organic frameworks (HOFs), metal-organic frameworks (MOFs), and porous organic polymers (POPs). The subfield of chemistry specializing in porous polymers is called reticular chemistry.

Covalent organic frameworks

See main article: Covalent organic framework. Covalent organic frameworks are crystalline porous polymers assembled from organic monomers linked through covalent bonds.^[1]

Hydrogen-bonded organic frameworks

See main article: Hydrogen-bonded organic framework. Hydrogen-bonded organic frameworks are crystalline porous polymers assembled from organic monomers linked through hydrogen bonds.^[2]

Metal-organic frameworks

See main article: Metal-organic framework. Metal-organic frameworks are crystalline porous polymers assembled from organic monomers connected by coordination to metal atom centers.^[3]
