The use of porous materials to store/deliver natural gas (mostly methane) in vehicles requires large amounts of methane being stored per unit volume In this work, we report several porous metal-organic frameworks (MOFs) with NOTT-101 type structures, containing Lewis basic nitrogen sites through the incorporation of pyridine, pyridazine, and pyrimidine groups into the organic linkers. They exhibit significantly higher total volumetric methane storage capacities (∼249-257 cm3 (STP) cm-3 at room temperature (RT) and 65 bar) than NOTT-101a (here the MOF abbreviation with “a” at the end represents the fully activated MOF). The most significant enhancement was observed on UTSA-76a with functional pyrimidine groups (237 cm3 (STP) cm-3 in NOTT-101a vs. 257 cm3 (STP) cm-3 in UTSA-76a). Several multivariate (MTV) MOFs constructed from two types of organic linkers (pyrimidine-functionalized and unfunctionalized) also show systematically improved methane storage capacities with increasing percentage of functionalized organic linkers. The immobilized functional groups have nearly no effect on the methane uptakes at 5 bar but significantly improve the methane storage capacities at 65 bar, so the reported MOFs exhibit excellent methane storage working capacities of ∼188-197 cm3 (STP) cm-3. The experimental process involved the reaction of 5,5′-(Pyridine-2,5-diyl)diisophthalic acid(cas: 1431292-15-7).Recommanded Product: 5,5′-(Pyridine-2,5-diyl)diisophthalic acid

S.; Barros, Amanda L.; Alves, Severino Jr.; Li, Bao-Hong; Ren, Fei; Batten, Stuart R.; Soares, Thereza A. published an article in 2015, the title of the article was A combined experimental and computational study of novel nanocage-based metal-organic frameworks for drug delivery.Quality Control of 5,5′-(Pyridine-2,5-diyl)diisophthalic acid And the article contains the following content:

Three new metal organic frameworks (MOFs) with chem. formulas [(CH3)2NH2] [Sm3(L1)2(HCOO)2(DMF)2(H2O)]·2DMF·18H2O (1), [Cu2(L2)(H2O)2]·2.22DMA (2) and [Zn2(L1)(DMA)]·1.75DMA were synthesized and structurally characterized. 1 and 2 show a classical NbO-like topol. and have two types of interconnected cages. 3 exhibits an uncommon zzz topol. and has two types of interconnected cages. These MOFs can adsorb large amounts of the drug 5-fluorouracil (5-FU) and release it in a progressive way. 5-FU was incorporated into desolvated 1, 2 and 3 with loadings of 0.40, 0.42, and 0.45 g g-1, resp. The drug release rates were 72%, 96% and 79% of the drug after 96 h in 1, 120 h in 2 and 96 h in 3, resp. Grand Canonical Monte Carlo (GCMC) simulations were performed to investigate the mol. interactions during 5-FU adsorption to the three novel materials. The GCMC simulations reproduced the exptl. trend with respect to the drug loading capacity of each material. They also provided a structural description of drug packing within the frameworks, helping to explain the load capacity and controlled release characteristics of the materials. 5-FU binding preferences to 1, 2 and 3 reflect the diversity in pore types, chem. and sizes. The calculated drug load is more related to the mol. properties of accessible volume Vacc than to the pore size.

And the article contained the following:

Two porous metal-organic frameworks (MOFs) incorporating pentanuclear Yb(III) clusters and pyridyl-supported tetracarboxylates or pyridyl carboxylic acid-supported tetracarboxylates, Yb-DDPY and Yb-DDIA, are presented, in which the pentanuclear Yb(III) cluster shows uncommon trigonal bipyramidal geometry. Furthermore, the pentanuclear Yb(III) clusters are extended by tetracarboxylates to form a 3D porous framework with uniform M12L8-cages constructed by 12 pentanuclear Yb(III) clusters and 8 tetracarboxylates with the size of ∼20 Å × 17 Å. Their highly CO2 uptake capacity and the existence of Lewis acidic sites make these MOFs promising catalysts for the chem. conversion of CO2. These MOFs demonstrate good catalytic activities and recyclability in the cycloaddition of CO2 and epoxides at 60° under 1.0 MPa pressure or at room temperature and atm. pressure. In addition, the synergistic effect of the Bronsted acidic -COOH groups and the Lewis acidic Yb(III) sites makes Yb-DDIA exhibit higher catalytic activity towards the cycloaddition of CO2 and epoxides. The experimental process involved the reaction of 5,5′-(Pyridine-2,5-diyl)diisophthalic acid(cas: 1431292-15-7).Recommanded Product: 1431292-15-7
