This compound is a benzonitrile with two fluorine substituents positioned ortho to the nitrile group, activating the ring toward nucleophilic aromatic substitution with silylated diphenols — the standard route to polyarylene ether nitrile engineering polymers.
This compound is manufactured into polyarylene ether nitrile (PEN) copolymers used as high-performance engineering plastics, including specialized porous membrane materials demonstrated for heavy-metal (lead) removal from wastewater.
