Abstract
We report the synthesis of a new 3,4-ethylenedioxythiophene monomer functionalized by a sulphonate group. Its electrochemical polymerization in water allows the generation of water-soluble oligomers. Furthermore the electrochemical polymerization of an equimolar aqueous solution of this new monomer and the unsubstituted one produces a polymer film having permanent cation-exchange properties. This phenomenon has been investigated with hexamine ruthenium(III) and uranyl cationic species using electrochemical and radiochemical methods.
