4-({2,4-Bis[(4-chlorophenyl)sulfonyl]phenyl}thio)benzenesulfonic acid was synthesized based on the scheme suggested from the results of retrosynthetic analysis. This compound is a new monomer for the preparation of sulfonated poly(arylene ether sulfones) used as a solid polymer electrolyte in fuel cells. The structure of the aromatic disulfone containing a sulfo group was suggested based on the data on the influence of chemical structure of structural elements of polysulfone proton-conducting membranes on their operational characteristics.
