FTIR and 1 H NMR spectroscopy were used to confirm the presence of the agZIF-62 phase in the blends. The 1 H NMR spectra of the blends displays all hydrogen environments of the benzimidazole and imidazole linkers, with a similar ratio of H1 to H2 (Figures ). A minor decrease in this ratio was observed in the 1:6 blend spectrum.
