Metal-organic frameworks (MOFs) are an emerging class of porous materials created by the assembly of inorganic connectors and organic linkers. They have potential applications in fields such as gas storage as well as separation, sensing, catalysis, and drug delivery due to its properties such as flexibility, porosity, high surface area and functionality. Among the various synthetic approaches for the preparation of MOFs, solvothermal and microwave-assisted methods are of particular importance, and hence have been used frequently. They have been recently used as heterogeneous catalysts in Friedel-Crafts reactions, condensations reactions, oxidations, coupling reactions, etc. However, owing to the low thermal stability and moisture sensitivity, their catalytic applications are limited. This short review covers recent developments in the synthetic methods employed for the preparation of MOFs as well as their catalytic applications.

“…In this regard, the synthesis of new cobalt‐based materials using the multifunctional ligand, 5,5′‐(diazene‐1,2‐diyl)diisophthalic acid (H 4 ABTC) has been explored over the last years . The coordination chemistry of H 4 ABTC is interesting since its four carboxylate groups can be partially or completely deprotonated in order to generate H 2 ABTC 2− , HABTC 3− , and ABTC 4− anions under different synthesis conditions that can coordinate with metal ions in multiple ways.…”

A novel URJC-3 material based on cobalt and 5,5'-(diazene-1,2diyl)diisophthalate ligand, containing Lewis acid and basic sites, has been synthesized under solvothermal conditions. Compound URJC-3, with polyhedral morphology, crystallizes in the tetragonal and P4 3 2 1 2 space group, exhibiting a three-dimensional structure with small channels along a and b axes. This material was fully characterized, and its hydrogen adsorption properties were estimated for a wide range of temperatures (77-298 K) and pressures (1-170 bar). The hydrogen storage capacity of URJC-3 is quite high in relation to its moderate surface area, which is probably due to the confinement effect of hydrogen molecules inside its reduced pores of 6 Å, which is close the ionic radii of hydrogen molecules. The storage capacity of this material is not only higher than that of active carbon and purified single-walled carbon nanotubes, but also surpasses the gravimetric hydrogen uptake of most MOF materials.

A new thermally highly stable 2D coordination polymer, formulated as [Co(μ6-abtc)0.5(μobix)]n (abtc = dioxygenated form of 3,3′,5,5′-azobenzenetetracarboxylate) obtained employing the semi-flexible 1,2-bis(imidazole-1-ylmethyl)benzene (obix) linker in hydro(solvo)thermal method. The complex was characterized by various techniques such as IR spectroscopy, elemental analysis, single crystal and powder crystal analysis. Crystallographic study of complex 1 reveal that two metal(II) ions are linked by O atoms of carboxylate groups of abtc ligand to build paddle-wheel SBU (secondary building unit). These SBUs are stabilized by the connection of obix ligand. The Co(II) ions are µ6-bridged by hexadentate abtc ligand to generate 2D polymer layers with 3,4-connected binodal net (point symbol {4.6 2 }2{4 2 .6 2 .8 2 }) and topological type is 3,4L13. Thermal analysis shows that complex 1 thermally stable up to 401 °C.
