Preparation of dibromopyridines having –(CH2)m–SO3Na groups as monomers for new polypyridines

Abstract Dibromopyridines or dibromopyridone with –(CH 2 ) m –SO 3 Na group(s) has been prepared via the reactions of the corresponding dibromopyridines with –OH and –NH 2 groups with sultone. These compounds were converted into polymers with the –(CH 2 ) m –SO 3 H groups via organometallic polycondensation. The polymer showed proton conducting properties and high stability toward oxidation.
