The object of this research is the synthesis of a diazonium perfluorocyclobutane (PFCB) monomer, with the ultimate goal for a diazonium PFCB polymer. The polymer is designed as an alternative electrolyte for Nafion® polymer, a commonly employed material in proton exchange membrane (PEM) fuel cells. Currently, we are trying to improve the chlorosulfonation of 4,4'-di(2-bromoterafluoroethoxy)biphenyl by using Thionyl chloride with chlorosulfonic acid. The progress of the reaction and the purity of the final product are monitored through diverse characterization techniques, including thin layer chromatography (TLC), proton/fluorine nuclear magnetic resonance (NMR), and infrared spectroscopy (IR).
