ABSTRACT:
A fluorinated sulfonamide small molecule having the general structurewherein m, n and p are 0 to 3, with the proviso that m+n+p is equal to 1 to 4;A1is an aromatic heterocyclic group, with the proviso that carbon atoms of the heterocyclic ring are fully substituted by fluorinated sulfonamide groups; andR1, R2, and R3are linear or branched perfluoroalkylene groups, optionally containing oxygen, chlorine, bromine, or iodine atoms. Polymers and small molecules useful in making polymer electrode membranes, membrane electrode assemblies, and electrochemical cells, such as fuel cells, are also described.
