摘要 :
Three new water-stable In(III)-based metalorganic frameworks, namely, [In-3(TTTA)(2)(OH)(3)(H2O)]center dot(DMA)3 (BUT-70, DMA = N,N-dimethylacetamide), [In-3(TTTA)(2)(CH3O)(3)] (BUT-70A), and [In-3(TTTA)(2)(OH)(3)] (BUT-70B), with rod-shaped secondary building units (SBUs) and an new acrylate-based ligand, (2E,2'E,2 '' E)-3,3',3 ''-(2,4,6-trimethylbenzene-1,3,5-triyl)-triacrylate (TTTA(3)) were obtained and structurally characterized. BUT-70A and -70B were generated in a single-crystal to single-crystal transformation fashion from BUT-70 through guest exchange followed by their removal. The solvents used for guest exchange were methanol and dichloromethane, respectively. Single-crystal structure analyses show that the guest exchange and removal process is accompanied by the substitution of coordinated water molecules of In(III) centers with uncoordinated carboxylate O atoms of TTTA(3) ligands. Moreover, hydroxyl groups bridging two In(III) centers are also replaced by methoxyl groups in the transformation from BUT-70 to -70A. Overall, three metalorganic frameworks (MOFs) are constructed by infinite chains consisting of corner-sharing InO4(OR)(2) (R = H or Me) octahedral entities, which are interconnected by TTTA(3) ligands to form three-dimensional frameworks. Unlike most reported MOFs with infinite chains as SBUs, such as well-known MIL-53 and M-MOF-74, which have one-dimensional channels along the chain direction, the BUT-70 series contain two-dimensional intersecting channels. The BrunauerEmmettTeller surface area and pore volume of BUT-70A were estimated to be 460 m(2) g(1) and 0.18 cm(3) g(1), respectively, which are obviously lower than those of BUT-70B (695 m(2) g(1) and 0.29 cm(3) g(1)). Gas adsorption experiments demonstrated that BUT-70A and -70B are able to selectively adsorb C2H2 over CO2 and CH4. At 1 atm and 298 K, BUT-70A uptakes 3.1 mmol g(1) C2H2, which is 3.6 times that of the CO2 uptake and 7.2 times that of the CH4 uptake. Compared with BUT-70A, BUT-70B presents an even higher C2H2 uptake of 3.9 mmol g1 at the same conditions, but slightly lower Ideal Adsorbed Solution Theory C2H2/CO2 and C2H2/CH4 selectivities.

摘要 :
Antibiotics and organic explosives are among the main organic pollutants in wastewater; their detection and removal are quite important but challenging. As a new class of-porous materials, Metal organic frameworks (MOPs) are considered as a promising platform for the sensing and adsorption applications. In this work, guided by a topological design approach, two stable isostructural Zr(IV)-based MOFs, Zr6O4(OH)(8)(H2O)(4)(CTTA)(8/3) (BUT-12, H(3)CTTA = 5'-(4-carboxyphenyl)-2',4',6'-trimethyl-[1,1':3',1 ''-terphenyl]-4,4 ''-dicarboxylic acid) and Zr6O4(OH)(8)(H2O)(4)(TTNA)(8/3) (BUT-13, H(3)TTNA = 6,6',6 ''-(2,4,6-trimethylbenzene-1,3,5-triyl)tris(2-naphthoic acid)) with the the-a topological structure constructed by D-4h 8-connected Zr-6 clusters and D-3h 3-connected linkers were designed and synthesized. The two MOFs are highly porous with the Brunauer-Emmett-Teller surface area of 3387 and 3948 m(2) g(-1), respectively. Particularly, BUT-13 features one-of the most porous water-stable MOFs reported so far. Interestingly, these MOFs, represent excellent fluorescent properties, which can be efficiently quenched by trace amounts of nitrofurazone (NZF) and nitrofurantoin (NFT) antibiotics as well as 2,4,6: trinitrophenol (TNP) and 4-nitrophenol (4-NP) organic explosives in water solution. They are responsive to NZF and TNP at parts per billion (ppb) levels, which are among the best performing luminescent MOP-based sensing materials. Simultaneously, both MOFs also display high adsorption abilities toward these organic molecules. It was demonstrated that the adsorption plays an important role in the preconcentration of analytes, which can further increase the fluorescent quenching efficiency. These results indicate that BUT-12 and -13 are favorable materials for the simultaneous selective detection and removal of specific antibiotics and organic explosives from water, being potentially useful in monitoring water quality and treating wastewater.

摘要 :
Through ligand modification, we have replaced the central benzene ring of H2TDBA ([1,1': 3', 1.-terphenyl]-4,4.-dicarboxylicacid) with the pyridine structurally related ligand H2PDDA (4,4'-(pyridine-2,6-diyl) dibenzoic acid), which makes the central pyridine ring of H2PDDA more coplanar with two benzene rings on both sides of the ligand. The modification results in a dramatically different linkage configuration, thereby allowing structural changes to the metal-organic frameworks (MOFs). Two 2-D MOFs, [Cu(TDBA)(DMA)2].H2O (BUT-221, DMA = N,N-dimethylacetamide), and [Cu 3 (PDDA) 3 (DMA) 2 (H2O)].5H2O (BUT-223) have been synthesized through reactions of two ditopic carboxylate ligands with Cu(NO3)2.3H2O under solvothermal conditions, and characterized by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis and infrared spectroscopy. Topological analysis shows that BUT-221 is a twofold parallel interpenetrating 44 2-D network with a skl topology, while BUT-223 is a 2-D network with a kgm topology.
