A novel monomer composition and a process of synthesizing the novel monomer is described. Generally, such novel monomers have an aliphatic spacer unit between two phenyl rings. In one embodiment the inventive monomer has a general structure of: wherein X and X' independently include a functional group selected from the group consisting of hydroxy, halogen, nitro, carboxylic acid, trimethylsiloxy and amines; G and G' independently include one selected from the group consisting of hydrogen, sulfonic acid, phosphoric acid, carboxylic acid, sulfonamide, and imidazole; "m" and "o" being integers and each independently having a value in the range from 0 to 15. The aliphatic spacer unit in alternative described embodiments of the inventive monomer does not contain the fluorinated methylene unit. Novel processes of synthesizing such monomers are also described. Based on these inventive monomer compositions, inventive polymer structures and processes of synthesizing them are also described.
