Figure 2. Versatility and scope of the three-layer synthesis strategy to produce two-dimensional MOF nanocrystals.

Figure 2

a-d, Scanning electron microscopy (SEM) images of CuBDC crystals synthesized via the three-layer approach at a, 298 K, b, 313 K, c, 323 K and d, 333 K. e-h, SEM micrographs of two-dimensional crystals obtained by extending the same synthesis strategy to other metal-organic-frameworks, i.e. e, cobalt 1,4-benzenedicarboxylate or CoBDC, f, zinc 1,4-benzenedicarboxylate or ZnBDC, g, copper 1,4-naphthalenedicarboxylate or Cu(1,4-NDC) and h, copper 2,6-naphthalenedicarboxylate or Cu(2,6-NDC). Insets in panels e-h display the corresponding X-ray diffractograms recorded for the 2D MOF crystals.
