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
Covalent organic frameworks are crystalline porous polymers assembled from organic monomers linked through covalent bonds.
Hydrogen-bonded organic frameworks
Hydrogen-bonded organic frameworks are crystalline porous polymers assembled from organic monomers linked through hydrogen bonds.
Metal-organic frameworks
Metal-organic frameworks are crystalline porous polymers assembled from organic monomers connected by coordination to metal atom centers.
