摘要：

Each the same: A stable, recoverable, amorphous phase (see topology model) was produced by heating each of four different zeolitic imidazolate frameworks ZIF-1, -3, -4, and Co-ZIF-4. By comparing nanoindentation results, density measurements, and X-ray total scattering results, it is concluded that the structure of the amorphous phase is equivalent in each case. Amorphization was only observed in ZIFs encompassing unsubstituted imidazolate ligands. (Figure Presented). © 2011 Wiley-VCH Verlag GmbH & Co. KGaA.
