Figure 14. (A) Scheme for the preparation of layered less Cu(dhbc)2(bpy) · H2O MONs at the air/water interface. (B) AFM image of Cu(dhbc)2(bpy) · H2O MONs. Inset: height profiles of MONs corresponding to the three labeled lines. (C and D) TEM and HRTEM image of Cu(dhbc)2(bpy) · H2O MONs. (E) Schematic illustration of SDA strategy for the synthesis of CoNi-MOFNA, (F) SEM image. (G) TEM image. (H) AFM image. (I) Formation of isolated, anisotropically shaped DUT-134(Cu) ·DMF microcrystals. (J) Spontaneous self-assembly of the microcrystals into face-to-face or edge-to-face arrangements in fresh DMF solution. (K and L) Freestanding carpets and spontaneous roll-ups resulting in lengths up to ca. 100 µm in diameter and up to 20 mm or longer. Bottom: (I) SEM image of a DUT-134(Cu) flake. (J) surface of the carpet. (K) macrostructure of the dried carpet. Photos: (L) Translucent DUT-134 carpet in DMF (left) and large “multi-walled” macro-tubes in DMF (right).
