Typical monomers with reactive -Br group for the synthesis of amorphous POFs
using aryl-aryl Yamamoto coupling, aryl-aryl Suzuki coupling, Sonogashira-Hagihara coupling,
Heck coupling reactions
long-ordered range structure of POFs is due to the distortion of the construct-
ing units and kinetics controlled irreversible coupling process. Compared with
soluble polymers and crystalline organic porous frameworks, the structural char-
acterizations of POFs are relatively complicated due to their insolubility and
amorphous nature. It requires much effort to unambiguously characterize the
structure of POFs by the combination of various chemical analytical methods.
