Fig. 2. Time resolved diffractograms with their temperature profiles for crystallisation of the (a) kat polymorph of ZIF-8 from the amorphous matrix and (b) crystallisation directly into the dia polymorph. Homogeneity and uniformity of the reaction mixture is evident from the uniformity of the diffraction signal from crystalline silicon (at 2.6° in 2theta) which was used as an internal scattering standard.22.
