“…For the equimolar C 2 H 2 –CO 2 mixtures, CO 2 eluted first at 5.9/13.5 min g –1 , while C 2 H 2 was not detected until at 34.5/64.2 min g –1 at 298 and 273 K (Figure c,d). The breakthrough time ratio between C 2 H 2 and CO 2 reached 5.9, exceeding most of the reported MOFs (Figure b), such as JXNU-5 (4.7), Ca(dtztp) 0.5 (3.5), SNNU-27-Fe (3), Ni(tzba) 0.5 (F) (bpy) (2.7), Cu 0.5 (tztp) 0.5 (3), NbU-10 (1.5), FJU-36a (2.4), JCM-1 (3.8), JNU-1 (2), FJI-H33 (1.8), ZJU-74 (1.8), FJU-90a (2), and UPC-80 (2.6) Figure c,d).…”

Herein, we used the 4-fluoro-[1,1′-biphenyl]-3,4′,5-tricarboxylic acid (H3fbptc) ligand to design and construct a new metal–organic framework (MOF), [Cu3(fbptc)2(H2O)3]·3NMP (1), which possesses rich accessible metal sites and F functional groups in the porous walls and shows high uptake for C2H2 (119.3 cm3 g–1) and significant adsorption selectivity for C2H2 over CH4 (14.4) and CO2 (3.6) at 298 K and 100 kPa. In particular, for the gas mixtures of C2H2–CH4 and C2H2–CO2, the MOF reveals large breakthrough time ratios (C2H2/CH4 = 13, C2H2/CO2 = 5.9), which are particularly prominent in dynamic breakthrough experiments, also confirming the excellent potential for the practical separation of C2H2 from two-component mixtures (C2H2–CH4 and C2H2–CO2) and even three-component mixtures (C2H2–CO2–CH4).

“…3f). [34][35][36][37][38][39][40][41][42][43] For the C 2 H 2 /CO 2 (50 : 50) mixture with a total ow of 2 mL min −1 , the breakthrough time of SNNU-505-Zn reached 48 min g −1 (273 K) and 33 min g −1 (298 K). Therefore, all the breakthrough results present that SNNU-505-Zn can efficiently separate C 2 H 2 /C 2 H 4 and C 2 H 2 /CO 2 mixtures.…”

“…Metal–organic frameworks (MOFs) have been studied for many different applications in areas such as energy storage, − catalysis, − gas separations, − chemical sensing, , biomedical imaging, and drug delivery. − There is growing interest in polynuclear metal clusters as secondary building units (SBUs) for the formation of highly connected metal–organic frameworks such as UiO-66. − The rare-earth (RE)-based MOFs with their unusually high coordination number readily form MOFs especially with dimers or chains. − Interestingly, the addition of a modulator leads to higher-nuclearity RE clusters . Kitagawa and co-workers coined the term “coordination modulation” for monocarboxylic acid modulators to control the morphology of MOF crystals. , Organic carboxylic acids like benzoic, acetic, formic, and trifluoroacetic acid can compete with a linker for coordination to the metal.…”

A new fluoro-bridged rare-earth (RE) metal−organic framework consisting of 15-connected nonanuclear and 9-connected trinuclear clusters {[RE 9 -(μ 3 -F) 14 (H 2 O) 6 ][RE 3 (μ 3 -F)(H 2 O) 3 ](HCO 2 ) 3 -(BTB) 6 }•(solvent)x 2 (RE = Ho 3+ and Gd 3+ ) was synthesized through the transformation of a dimeric complex formulated as bis(2,2′-bipyridine)tetrakis(μ-2-fluorobenzoato-O,O′)-bis(2fluorobenzoato)diRE(III) 1 with the bridging linker 1,3,5-tris(4-carboxyphenyl)benzene (H 3 BTB). The rare-earth metal ions Ho 3+ and Gd 3+ were also found to remove fluorine from other organo-fluorine compounds such as perfluorohexanoic acid (PFHxA) and perfluorooctanoic acid (PFOA), resulting in the new fluorobridged RE-MOFs.
