Novel Supramolecular Polymers Novel compositions
are proposed that contain phosphonium cations and
nucleic acid building blocks using simple
derivatizations of petroleum based monomers.
These monomers provide branched and linear block
copolymers wherein the intermolecular
interactions enable self-healing and hydroxide
anion transport in alkaline fuel cells.
Tailored intermolecular interactions, including
novel cationic polyelectrolytes and nucleobase
hydrogen bonding, will dramatically influence the
performance of smart or self-healing coatings and
the transport of anions in alkaline fuel cell
membranes for alternate energy technologies. Our
research program also identified a new family of
ion-containing polymers that combined nucleobase
hydrogen bonding and associated pendant organic
cations for the formation of reversible,
ion-channeled, macromolecular architectures.
