Zeolite-like metal–organic frameworks (ZMOFs): design, synthesis, and properties

Abstract

This review highlights various design and synthesis approaches toward the construction of ZMOFs, which are metal-organic frameworks (MOFs) with topologies and, in some cases, features akin to traditional inorganic zeolites. The interest in this unique subset of MOFs is correlated with their exceptional characteristics arising from the periodic pore systems and distinctive cage-like cavities, in conjunction with modular intra- and/or extra-framework components, which ultimately allow for tailoring of the pore size, pore shape, and/or properties towards specific applications.

Low concentration CO2 capture using physical adsorbents: Are metal–organic frameworks becoming the new benchmark materials?

“…Overall, work on the rational design, development and synthesis of MOFs that target particular applications remains scarce. [20][21][22][23][24] To evaluate the performance of various adsorbents, we selected a series of materials from each family to compare their adsorption properties in terms of porosity, gravimetric/volumetric uptake (at low CO 2 concentrations up to 50 % and a total pressure of 1 bar, in balance with N 2 and CH 4 and H 2 ), energetics, selectivity, stability and tolerance to water vapor. We also describe the physical separation mechanisms involved in the most promising CO 2 adsorbents.…”

Chemistry of Metal-organic Frameworks Monitored by Advanced X-ray Diffraction and Scattering Techniques

“…68 However, successful crystal structure determination based on the data obtained from microdiffraction setups is at present still in large extend limited by the loss of microbeam intensity and the loss of crystallinity under highly focused beams. On the other hand, the crystal structure of bimetallic [Ca(H 2 O) 6 ].…”

“…In this context, MOF structures with the targeted structural features can be designed. [6][7][8][9][10][11] Specific three-dimensional connectivity of inorganic and organic units enables the formation of MOF architectures with low framework densities (from 0.2 g/cm 3 ), high void volumes (up to 90%) and unprecedented internal specific surface areas (6000 m 2 /g). Thus MOFs are to a large extent investigated for gas or liquid adsorption and separation.…”

Cs7Sm11[TeO3]12Cl16 and Rb7Nd11[TeO3]12Br16, the new tellurite halides of the tetragonal Rb6LiNd11[SeO3]12Cl16 structure type

“…These slabs interleave with either sheets formed by halide anions, or more complex cation-deficient metal-halide layers chopped from the structures of CsCl, FeSe Table 1. First observed among selenites, this family has been recently extended by us into the realm of tellurites; we also successfully introduced novel NaCl-type [Cd 6 Cl 24 ] metal-halide blocks [14].…”

“…As yet, a priori construction of the desired structure motifs and prediction of the best chemical compositions is not feasible in general, not the least due to complexity and versatility of both the architectures and the compositions themselves. Significant developments have been achieved in the area of hybrid metal-organic frameworks [6,7] where both the metal cation and the organic linkers or templates determine the resulting structures. An alternative approach has been developed for the pure inorganics, which is based on the so-called "saltinclusion solids".…”
