Two particular interesting groups of functionalized polymeric materials are the polyampholytes and polyelectrolytes. These materials offer the versatility to complex different metal ions due to the presence of azole and/or carboxylate groups in the structure. In particular, in the Cu(II)-Polymer complexes containing imidazole, the heterocyclic ring has been found to be the main group involved in metal ion uptake and the carboxylic group appears to have a coordinating role only at high concentrations of the metal ion from the 13C CP-MAS spectra. The aim of the present work was to determine the effects of copper ion at different concentrations in the molecular dynamics and to study the coordination behavior in synthetic polymers bearing imidazole, triazole or pyrazole and carboxylic acid by 1D- and 2D-solid-state NMR experiments.
