The invention relates generally to monomers comprising superacidic functional groups. The superacidic functional groups comprise fluorinated sulfonate moieties. Monomers provided by the present invention include dihydroxy aromatic compounds, aromatic diamines, aromatic dicarboxylic acids, aromatic diacarboxylic acid esters, aromatic dithiols, and monomers comprising mixed functionalities, for example monomers comprising an aromatic amine group and an aromatic hydroxyl group. The monomers provided by the present invention are useful in the preparation of novel polymers comprising superacidic functional groups, materials useful in membrane applications. The superacidic functional groups present in the polymer compositions impart excellent proton conductivities. In one embodiment, the present invention provides monomers which may be used to prepare polymers useful as materials for polymer electrolyte fuel cell membranes.
