“…5e). The value of C 2 H 2 /CH 4 selectivity for compound 1 is just lower than those of ZJU-195 (43.4) [46] and FJI-C1 (39.3) [52], but higher than other porous materials like ZJU-30 (9.59) [51], UTSA-222a (16) [53] and BUT-70B (23.3) [54]. Moreover, the selectivity of C 2 H 2 versus CH 4 can be further improved to 107.7 when the operation temperature is decreased to 273 K. Apparently, compound 1 is a promising adsorbent for the upgrading of fairly.…”

The energy-efficient purification of methane from C 2-hydrocarbons is of great significance for the upgrading of natural gas. So does the capture of carbon dioxide for remission of greenhouse effect. It is well established that some functional sites, such as open metals sites, Lewis basic nitrogen sites and fluorine groups, have shown significantly enhanced affinity toward more polarizable molecules. Thus, a water-stable Eu 3+-based fcu-metal-organic framework (MOF) (compound 1) with amino functional groups has been successfully constructed through a reticular chemistry approach. As a result, the activated compound 1 exhibits moderately high uptakes of C 2-hydrocarbons, but a less obvious adsorption of CH 4 at the same conditions. Among them, the adsorption capacity of C 2 H 2 is up to 143.6 cm 3 cm −3 and a relatively high selectivity of C 2 H 2 /CH 4 (107.7) is obtained at near room temperature. Moreover, compound 1 is also validated as an exceptional adsorbent for CO 2 capture, with the fairly high capacity of CO 2 (92.6 cm 3 cm −3) and CO 2 /N 2 selectivity (151.7) at ambient conditions. The excellent performance of compound 1 is mainly driven by the exposed amino functional groups within the contracted pores. Such effect thus leads to the achievement of dual-functional platform for methane purification and carbon dioxide capture. Furthermore, compound 1 features a satisfactory water stability, which is confirmed by the powder X-ray diffraction (PXRD) analysis and the retest of porosity after being soaked in water.

“…Metal-organic frameworks (MOFs) have attracted great interests due to the fluorescent properties [1][2][3][4][5], as well as the significant applications, such as magnetism [6][7][8], gas adsorption and separation [9][10][11], sensors or detectors [12][13][14][15][16][17], proton conduction [18], etc. Lanthanide coordination polymers including lanthanide-organic frameworks, one of the important MOFs, are generally synthesized by hydrothermal methods which require high pressure and high temperature that has impeded scalable synthesis of lanthanide MOFs and their industrial utilization [19][20][21].…”

A novel Tb(III) metal-organic framework was synthesized by a multi-layer diffusion method at room temperature. Adjacent Tb(III) ions were connected together by bridging carboxylic groups to construct one-dimensional chains and the metal-organic framework based on these parallel 1D chains was formed through thiophene-2,5-dicarboxylate bridges. UV-Vis and fluorescent emission spectra as well as theoretical calculation showed that organic ligands acted as sensitizers to Tb(III) fluorescence. With the excitation of 325 nm, the emission peaks of this compound were found at 488, 545, 587, and 621 nm which were attributed to 5

“…3 Moreover, hydroxyl ligands derived from water molecules binding to metal clusters, have been exploited for their Lewis and/or Brønsted acidity in catalytic reactions. 4,5 Therefore, lanthanide-based metal-organic frameworks (Ln-MOFs) are promising candidates for the applications of gas capture [6][7][8][9] and heterogeneous acid-catalyzed reactions. [10][11][12][13] The selective adsorption of CO2 and subsequent transformation into fine chemicals is receiving great interest due to these application's environmental implications.…”

Three new lanthanide-based metal–organic frameworks (Ln-MOFs), namely MOF-590, -591, and -592 constructed from a tetratopic linker, benzoimidephenanthroline tetracarboxylic acid (H4BIPA-TC), were synthesized under solvothermal conditions and fully characterized. All of the new MOFs exhibit three-dimensional frameworks, which adopt unprecedented topologies in MOF field. Gas adsorption measurements of MOF-591 and -592 revealed good adsorption of CO2 (low pressure, at room temperature) and moderate CO2 selectivity over N2 and CH4. Consequently, breakthrough experiments illustrated the separation of CO2 from binary mixture of CO2 and N2 with the use of MOF-592. Accordingly, MOF-592 revealed the selective CO2 capture effectively without any loss in performance after three cycles. Moreover, MOF-590, -591, and -592 showed to be catalytically active in the oxidative carboxylation of styrene and CO2 for a one-pot synthesis of styrene carbonate under mild conditions (1 atm CO2, 80 °C, and without solvent). Among the new materials, MOF-590 revealed a remarkable efficiency with exceptional conversion (96%), selectivity (95%), and yield (91%).
