제목 Sulfonated poly(phenylene)s containing p-benzophenone moiety for proton exchange membrane fuel cell (PEMFC)
초록 We focused on polyphenylene structure without ether linkage and tetraphenylethylene moiety for thermal and chemical stabilities in fuel cell operating system. Polyphenylene containing pendant benzoyl groups has a great of advantages, such as good durability, high performance amorphous thermoplastic, thermooxidative stability, excellent chemical and physical properties, and good solubility. Moreover, Tetraphenylethylene is a conjugated structure which enables to form planar conformation between aromatic rings, and selective sulfonation on phenyl rings of polymer side chain. The polymers were prepared by Nickel catalyzed carbon-carbon coupling reaction of dichlorotetraphenylethylene(DCTPE) and 2,5-dichloro-p-benzophenone. These polymers have all carbon-carbon linkages without any ether linkage on polymer backbone, It is enable to prevent polymer from attacked by nucleophiles. The sulfonic acid groups were introduced by sulfonation reaction with chlorosulfonic acid.
