a DSC data of the ZIF glass formers. b XRPD patterns of all investigated materials. The patterns are vertically offset for clarity. c Stacked plot of 1H NMR spectra of digested samples of the investigated amorphous materials (recorded in a solvent mixture of DMSO-d6 and DCl/D2O at room temperature). A zoom in the aromatic region is shown. The 13C satellite peaks of protons 1 and 2 are marked with asterisks (*). Weak signals not marked with asterisks belong to unidentified decomposition products. d X-ray total scattering data in the form S(Q) of the amorphous phases. For agZIF-4 and agZIF-zni sharp scattering features ascribed to ZnO impurities are highlighted in red. e XPDFs in form D(r) obtained from the S(Q) data shown in d. Data for agZIF-62 in panels d and e are taken from ref. 30.
