“…Metal–organic frameworks (MOFs) have aroused extensive interests, bceause of their intriguing topological structure and potential applications in industry, such as gas adsorption and separation, chemical sensing, luminescence, and catalysis. − In previous research, many extended ligands were designed and synthesized to construct MOFs with large pore size and high surface area. − However, the excessive empty space generated from extended ligands easily lead to the collapse of the framework. Interpenetration, which is referenced as catenation, can minimize the empty space and significantly enhance the stability of frameworks. − Although the interpenetrated motifs reduce the porosity, the interpenetrated MOFs materials still possess many unique properties, such as stepwise gas adsorption, guest-responsive porosity, and photoluminescence control. − Of these aspects, the characteristic of stepwise adsorption is attractive and deserves further exploration. The flexible interpenetrated materials with stepwise adsorption can be also vividly described as breathing MOFs. − Breathing MOFs cannot adsorb gas in their closed state, but the gas can pass through the gate at high pressure or low temperature.…”

A ZnO clusters based flexible doubly interpenetrated metal-organic framework [(ZnO)(DCPB)DMF]·2DMF·8HO (JLU-Liu33, HDCPB = 1,3-di(4-carboxyphenyl)benzene, DMF = N,N-dimethylformamide) with pcu topology has been solvothermally synthesized. Because of its flexible structure, JLU-Liu33 exhibits a breathing behavior upon N and CO adsorption at low temperature, and CH and CH adsorption at 273 and 298 K. Furthermore, by adopting the direct synthesis method, two isomorphic compounds-JLU-Liu33L and JLU-Liu33H-have been obtained by partial substituting Zn with different amounts of Co into the JLU-Liu33 framework. The gas adsorption study of Co-doped materials reveals that the gate opening effect of JLU-Liu33 can be modulated by introducing different contents of Co into ZnO clusters. Meanwhile, with the increasing amount of Co, the adsorption amount and isosteric enthalpy values for CO have been improved. It is worth mentioning that JLU-Liu33H exhibits commendable selectivity for CO over CH which may be a good candidate for industrial gas purification and air separation applications.

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.
