We have recently synthesized new polymeric materials with the characteristics of polyelectrolyte (Poly(EGDE-MAA) = A) or polyampholyte (Poly(EGDE-MAA-IM) = B) and their copper(II) complexes, respectively. The coordination behavior of the carboxylic acid of the MAA, compared to that provided by the imidazole ring, was studied through solid-state NMR and changes in the FTIR spectra.
