Porous polymer

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

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

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

Main article: Metal-organic framework

Metal-organic frameworks are crystalline porous polymers assembled from organic monomers connected by coordination to metal atom centers.[3]
