“…The resulting nanostructure contains microporous channels occupied by solvent molecules that are arranged perpendicularly to the aforementioned chains. A cross-section of these channels reveals that they are rectangular in shape having the dimensions 8.6 by 11.5 Å , which is in the range of similar channels observed in other metal-organic porous solids [39]. This type of molecular self-assembly has not been previously observed in any known mercuracarborand structures.…”

“…1 This has been achieved in crystalline zeolites 2 and in other extended networks and frameworks, such as metalorganic frameworks (MOFs), [3][4][5][6] covalent organic frameworks (COFs), 7,8 and organic polymer networks. [9][10][11] There is also growing interest in porous materials composed of discrete organic [12][13][14][15][16][17][18][19] or metal-organic [20][21][22][23] molecules.…”

Controlling the Crystallization of Porous Organic Cages: Molecular Analogs of Isoreticular Frameworks Using Shape-Specific Directing Solvents

Small structural changes in organic molecules can have a large influence on solid-state crystal packing, and this often thwarts attempts to produce isostructural series of crystalline solids. For metal-organic frameworks and covalent organic frameworks, this has been addressed by using strong, directional intermolecular bonding to create families of isoreticular solids. Here we show that an organic directing solvent, 1,4-dioxane, has a dominant effect on the lattice energy for a series of organic cage molecules. Inclusion of dioxane directs the crystal packing for these cages away from their lowest-energy polymorphs to form isostructural, 3-dimensional diamondoid pore channels. This is a unique function of the size, chemical function, and geometry of 1,4-dioxane, and hence a non-covalent auxiliary interaction assumes the role of directional coordination bonding or covalent bonding in extended crystalline frameworks. For a new cage, CC13, a dual, interpenetrating pore structure is formed which doubles the gas uptake and the surface area in the resulting dioxanedirected crystals.

“…1 Although MOFs are as porous as zeolites, the size, shape and adsorption performance of the pores are distinguishable. MOFs tend to be less thermodynamically stable than most inorganic microporous materials owing to the presence of organic linkers and hence are limited in conventional high-temperature catalyst applications.…”

Textured and house-of-card structures develop on the surfaces of cubic MOF-5 crystals. The formation mechanism of these novel constructions are investigated based on characterisation of the intermediate specimens with different reaction time intervals using scanning and transmission electron microscopies. It is found that the growth of MOF-5 cubic crystals does not follow the classical route. MOF-5 nanocrystallites initially aggregate to form large polycrystalline cubes, followed by surface rearrangement of the nanocrystallites into a textured structure consisting of nanowires lying along the [100], [010], [110] and [110] zone axes, if the face of the cube is defined to be (001). Further crystal growth leads to a house-of-cards structure constructed by interpenetrated nanoplates with their shortest axis parallel to [110] and [110] axes. Evidence of a reversed crystal growth process is also observed. MOF-5 cubes with a single crystal-like appearance are achieved with extended reaction times despite their hidden three tier structure containing varying porosities hidden underneath.
