Abstract
Disclosed herein are anion-conducting polymers that comprise a cationic benzimidazolium and imidazolium moieties. Methods of forming the polymers and membranes comprising the polymers are also provided.
Claims14
A polymer comprising one or more repeating units, wherein at least one of the repeating units comprises one or more benzimidazolium-containing moieties having Formula (I-A):
- wherein:
- R1 is independently selected from the group consisting of alkyl, perfluoroalkyl, heteroalkyl, alkoxy, perfluoroalkoxy, aryl, heteroaryl group and a polymer;
- R2 is alkyl;
- R2′, at each occurrence, is independently selected from the group consisting of hydrogen, and a polymer;
- R3 is independently selected from the group consisting of alkyl, perfluoroalkyl, heteroalkyl, aryl, aralkyl, and a polymer;
- and
- R5 is independently selected from the group consisting of hydrogen, and a polymer;
- wherein at least one of R1, R2′, R3, and R5 is a polymer.
