Abstract: Polymeric ion conductors composed of a polymeric matrix associated with an isoindolinium moiety represented by Formula I as described in the specification are provided. Anion conducting compositions comprising an anion conducting polymer associated with, or threaded within and having mechanically interlocked therearound, a cyclic moiety are also provided. lonomeric materials, including, for example, ion exchange membranes such as anion exchange membranes, made of the polymeric ion conductor and/or the anion conducting composition, and electrochemical systems and articles-of-manufacturing containing the polymeric ion conductor, the anion conducting composition or the ion exchange membrane are also provided.

Abstract: Polymeric ion conductors composed of a polymeric or co-polymeric backbone which comprises a plurality of backbone units, a metal ligand attached to at least a portion of the backbone units, and a metal ion attached to the metal ligand are provided. The metal ligand can be an N-heterocyclic carbene ligand and the metal can feature low oxophilicity. lonomeric materials, including, for example, ion exchange membranes such as anion exchange membranes, made of the polymeric ion conductor, and electrochemical systems and articles-of-manufacturing containing the polymeric ion conductor or the ion exchange membrane are also provided.

Abstract: Compositions comprising a tetraaryl ammonium salt, a tetraaryl ammonium salt covalently bound to a polymer and methods for manufacturing the same are disclosed. The disclosed compositions are useful e.g., for an anion exchange membrane, or an anion conducting polymer, and may further be used in electrochemical devices such as alkaline fuel cells, and alkaline redox-flow batteries.

Abstract: This invention is directed to intramolecular crosslinked polymer chains, commonly known also as single-chain polymer nanoparticles (SCPNs), with high resistance to mechanochemical bond scission and to uses thereof in solution.
