We applied advanced NMR techniques in solid state to study organic compounds and novel copper complexes of polyampholyte and polyelectrolyte polymeric structures. Remarkably, the copper-polyampholyte complex acts as an efficient heterogeneous catalyst for H2O2 activation and the degradation of Methyl Orange. Using 2D 1H-13C WISE NMR and proton spin-lattice relaxation times in the laboratory and rotating frame (TH1 and TH1rho), we analyzed the non-homogenous character of the doped and undoped materials. The effect of the paramagnetic ion in the structure of the polymers was also elucidated through these experiments.Additionally, 13C CP-MAS, 1H-13C HETCOR, and solution NMR spectra allowed us to conclude that the 2-carboxaldehydeimidazole molecule differed in the solution and in the solid-state after its synthetic process.
