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 stable hydroxide ion-exchange polymers. The polymers include ionenes, which are polymers that contain ionic amines in the backbone. The polymers are alcohol-soluble and water-insoluble. The polymers have a water uptake and an ionic conductivity that are correlated to a degree of N-substitution. Methods of forming the polymers and membranes including the polymers are also provided. The polymers are suitable, for example, for use as ionomers in catalyst layers for fuel cells and electrolyzers.

Abstract: The present disclosure provides alkaline-stable m-terphenyl benzimidazolium hydroxide compounds, in which the C2-position is attached to a phenyl group having various substituents at the ortho positions. Polymers incorporating m-terphenylene repeating groups derived from these alkaline-stable benzimidazolium hydroxide compounds are also presented, along with their inclusion in ionic membranes and in electrochemical devices.

Abstract: Described herein are crosslinked alkylated poly(benzimidazole) and poly(imidazole) polymer materials and devices (e.g., fuel cells, water electrolyzers) including these polymer materials. The polymer materials can be prepared in a convenient manner, allowing for applications such as anion exchange membranes (AEMs). The membranes provide high anion conductivities over a wider range of operating conditions when compared to the analogous membranes that are not cross-linked. The crosslinked polymer materials have improved alkaline stability, when compared to the analogous non-crosslinked polymer materials.
