Summary
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. The diazonium PFCB monomer synthesis is designed with 5 steps. Currently, we working on the coupling reaction (step 4) of 4,4’-bis (2-bromo-tetrafluoroethyoxy)- 3,3’-bis (chlorosulfonyl)-biphenyl and 4-acetamidobenzenesulfonamide with base catalyst N,N-Diisopropylethylamine (DIPEA). Specifically the objective is replacing the triethyl amine with DIPEA for an improved reaction. The progress of the reaction and the purity of the each step product are checked with diverse characterization techniques, including thin layer chromatography (TLC), and proton/fluorine nuclear magnetic resonance (NMR).
