Compound {(Me2NH2)3[Eu7(μ3-O)2(TBAPy)5(H2O)6]·12.5DMF} n (JXNU-5), constructed from the 1,3,6,8-tetrakis(4-carboxylphenyl)pyrene (TBAPy4–) ligand and one-dimensional (1D) europium carboxylate rods, is presented. JXNU-5 has a three-dimensional framework with 1D channels. The strong coordination bonds between EuIII ions with high charge densities and carboxylate O atoms as well as strong π···π-stacking interactions between pyrenes lead to a water-resistant JXNU-5, which was verified by powder X-ray diffraction and surface area measurements. The breakthrough simulations and experiments demonstrate that an efficient C2H2/CO2 (50/50 mixture) gas separation at ambient conditions was achieved with JXNU-5. The calculation results show that the dominating interactions between the absorbed C2H2 molecules and host framework are hydrogen bonds associated with the carboxylate O atoms exposed on the pores. Thus, an elegant example of a water-stable metal–organic framework for effective C2H2/CO2 separation is demonstrated.

“…Acetylene (C 2 H 2 ) is one of the significant fuel gas and essential raw materials in the petrochemical and electronic industries. , Nowadays, mainly there are two acetylene preparation processes, one is derived from the thermal cracking of natural gas (>80% CH 4 ) during which the separation of C 2 H 2 from CH 4 meets grade A requirement acetylene for organic synthesis, whereas the departure from the distillates produced during steam cracking in petroleum refining will produce a large number of byproducts (including CO 2 ). , However, the similarities between C 2 H 2 and CO 2 in the perspective of their shapes, molecular dimensions (3.3 × 3.3 × 5.7 and 3.2 × 3.3 × 5.4 Å 3 for C 2 H 2 and CO 2 , respectively), and physical properties (boiling points of 189.3 for C 2 H 2 and 194.7 K for CO 2 ) make it a great challenge for C 2 H 2 separation. Porous material-based adsorptive separation is considered to be a promising future separation technology with more environment friendly and energy efficient when compared with cryogenic distillation or organic solvent extraction. , Among all kinds of solid porous materials, − metal–organic framework (MOF) materials are considered to be the most promising candidates for such an application.…”

Additive-Induced Supramolecular Isomerism and Enhancement of Robustness in Co(II)-Based MOFs for Efficiently Trapping Acetylene from Acetylene-Containing Mixtures

Although supramolecular isomerism in metal-organic frameworks (MOFs) would offer a favorable platform for in-depth exploring their structure-property relationship, the design and synthesis of the isomers are still rather a challenging aspect of crystal engineering. Here, a pair of supramolecular isomers of Co(II)-based MOFs (FJU-88 and FJU-89) can be directionally fabricated by rational tuning the additives. In spite of the fact that the isomers have the similar Co secondary building units and organic linkers, they adopt distinct networks with acs and snw topologies, respectively, which derive from the conformational flexibility of the organic ligands. It is noteworthy that the porous structure of FJU-88 would be collapsed after removal of the solvent from the pores. But FJU-89a shows permanent porosity accompanied with unusual hierarchical micro- and mesopores and superior gas selective adsorption performance. In addition, FJU-89a can efficiently trap CH from CH/CO and CH/CH mixture gases through fixed-bed dynamic breakthrough experiments.

A new hybrid ultramicroporous material, [Ni(1,4-di(pyridine-2-yl)benzene)(CrO)] (DICRO-4-Ni-i), has been prepared and structurally characterized. Pure gas sorption isotherms and molecular modeling of sorbate-sorbent interactions imply strong selectivity for CH over CO (S). Dynamic gas breakthrough coupled with temperature-programmed desorption experiments were conducted on DICRO-4-Ni-i and two other porous materials reported to exhibit high S, TIFSIX-2-Cu-i and MIL-100(Fe), using a CH/CO/He (10:5:85) gas mixture. Whereas CO/CH coadsorption by MIL-100(Fe) mitigated the purity of trapped CH, negligible coadsorption and high S were observed for DICRO-4-Ni-i and TIFSIX-2-Cu-i.
