Abstract:
Subject polymers have a plurality of repeating units having amino- bis -phosphonate functionality pendent groups of a polyacrylate, polymethacrylate, polyacrylamide, polymethacrylamide, or linear polyethyleneimine. The polymers are prepared from a plurality of monomers comprising amino-te-phosphonate functionality or from a polymer having NHBoc or active ester pendent groups that are subsequently transformed into the amino-bis-phosphonate comprising polymer. The amino- bis -phosphonate comprising polymers or their precursor polymers can be prepared by RAFT polymerization or by transformation of a preformed polymer. The amino- bis -phosphonate comprising polymers can be linear or branched polymers. The amino- bis -phosphonate comprising polymers can be complexed with metal ions. The metal ions can be a radionuclide and the amino- bis -hosphonate comprising polymer complexes can be used as radiotherapeutic agents.

Abstract:
Polymers, polymer precursore, and other materials are described, having at least one heterocycle and being useful for fabrication of proton-exchange membranes (PEMs). In representative examples, the heterocycle is a fluorinated imidazole ring. The heterocycle can be chosen to have a low value of pKa, and may be a triazole ring, other nitrogen-containing heterocycle, or derivative thereof. Polymers and composites were prepared having excellent proton conductivity. Applications of these materials include fuel cells and other ion-conducting applications.
