Fig. 6. Morphological analysis of polyUiO-66 derived from pbdc-8a-COD1:1: (a) SEM of bulk crystals. (b and c) TEM of bulk crystals dispersed in methanol. Inset shows the spacing corresponds to UiO-66 crystals; (d and e) TEM of ultramicrotomed section. Arrows indicate the alternating layered assembly of metal rich and metal deficient structures. FFT shows the spacing at 1.2 nm that corresponds to UiO-66 (white arrows in (d) denote layered assemblies). (f) SAXS scattering profile of the bulk crystals showing a spacing at 4.5 nm; (g) PXRD powder pattern of the bulk material shows the spacing of UiO-66 at 1.2 nm.
