Abstract: Described herein are anionic phenylene oligomers and polymers, and devices including these materials. The oligomers and polymers can be prepared in a convenient and well-controlled manner, and can be used in cation exchange membranes. Also described is the controlled synthesis of anionic phenylene monomers and their use in synthesizing anionic oligomers and polymers, with precise control of the position and number of anionic groups.

Abstract: Described herein are branched and hyperbranched anionic phenylene polymers, produced with controlled incorporation of anionic substituents. Applications of such branched ionomeric polymers are also described herein. The branched ionomeric polymers are prepared by a convenient and well-controlled method, permitting tailored properties of catalyst ink formulations, ionomeric polymer membranes, and other applications. Such branched ionomeric polymers have applications in water purification, fuel cells, and battery products.
