High gas storage capacities and stepwise adsorption in a UiO type metal-organic framework incorporating Lewis basic bipyridyl sites
A UiO type MOF with Lewis basic bipyridyl sites was synthesized and structurally characterized. After being activated by Soxhlet-extraction, this MOF exhibits high storage capacities for H2, CH4and CO2, and shows unusual stepwise adsorption for liquid CO2 and solvents, indicating a sequential filling mechanism on different adsorption sites.

Structure Tuning of Metal Phosphonates: Syntheses, Structures and Characterizations of Two New Lead (II) Trisphosphonates
Two lead (II) trisphosphonates, [Pb3(H3L1)2(H2O)] (1) and [Pb5(HL2)(H3L2)(H4L2)(H2O)2][(H2O)2] (2), have been synthesized from two trisphosphonate ligands and characterized by EA, IR, UV–vis, TGA, powder and single-crystal X-ray diffraction methods. The single-crystal X-ray diffraction analyses reveal that they both feature three-dimensional framework structures. The lead (II) ions are mainly fiv...

A Series of Exceptionally Robust Luminescent Coordination Polymers based on a Bipyridinedicarboxylate Ligand and Rare Earth Metal Ions
A series of three-dimensional rare-earth coordination polymers, [M2(bpdc)3(H2O)4] (M = Y [1], Sm [2], Eu [3], Gd [4], Tb [5], Dy [6], Er [7], and Yb [8]) were synthesized by solvothermal reactions of 2,2′-bipyridine-5,5′-dicarboxylate (bpdc) with corresponding metal salts. Single-crystal and powder X-ray diffraction analyses demonstrated that these coordination polymers are isostructural. The ca...

An rht type Metal-Organic Framework based on Small Cubicuboctahedron Supermolecular Building Blocks and Gas Adsorption Properties
A metal–organic framework NPC-5 was synthesized via reaction of a methyl-functionalized ligand 2,4,6-trimethyl benzene-1,3,5-triyl-isophthalate (TMBTI) with Co(NO3)2·6(H2O) under solvothermal conditions. The steric hindrance induced by the methyl groups on the central phenyl ring led to a non-planar configuration of the ligand and further resulted in a small cubicuboctahedron SBB sustained...

Rationally tuned micropores within enantiopure metal-orgnic frameworks for highly selective separation of acetylene and ethylene
Separation of acetylene and ethylene is an important industrial process because both compounds are essential reagents for a range of chemical products and materials. Current separation approaches include the partial hydrogenation of acetylene into ethylene over a supported Pd catalyst, and the extraction of cracked olefins using an organic solvent; both routes are costly and energy consuming. Adso...

Protecting group and pore-discriminating adsorption properties of a hydrophilic-hydrophobic metal-organic framework,
Formed by linking metals or metal clusters through organic linkers, metal–organic frameworks are a class of solids with structural and chemical properties that mark them out as candidates for many emerging gas storage, separation, catalysis and biomedical applications. Important features of these materials include their high porosity and their flexibility in response to chemical or physical stimu...

Chemically Blockable Transformation and Ultra-selective Low Pressure Gas Adsorption in a Metal Organic Framework
Metal organic frameworks (MOFs) are among the most exciting materials discovered recently, attracting particular attention for their gas-adsorption and -storage properties. Certain MOFs show considerable structural flexibility in response to various stimuli. Although there are several examples of ''breathing'' MOFs, in which structural changes occur without any bond breaking, examples of transform...

Surface interactions and quantum kinetic molecular sieving for H-2 and D-2 adsorption on a mixed metal-organic framework material,
A rational strategy has been used to immobilize open metal sites in ultramicroporosity for stronger binding of multiple H2 molecules per unsaturated metal site for H2 storage applications. The synthesis and structure of a mixed zinc/copper metal?organic framework material Zn3(BDC)3[Cu(Pyen)] ·(DMF)5(H2O)5 (H2BDC = 1,4 benzenedicarboxylic acid and PyenH2 = 5-methyl-4-oxo-1,4-dihydro-pyridine...

Epoxidation of 1-butene to 1,2-butene oxide by transition metal disubstituted P-W-Mo ternary heteropoly quaternary ammonium salts
A series of transitional metal disubstituted ternary heteropoly quaternary ammonium salts, [TPA](4)H 3[PW7Mo3M2O38(H2O)(2)] (M = Mn, Co, Ni, Cu), were prepared by the reaction of the anion PW6Mo3O34 (9-) and the corresponding salts of the transitional metal in water, characterized by FI-IR, UV-Vis, XRD and TGA spectra, and appied to the epoxidation of 1-butene to 1,2-butene oxide (BO). The influ...

Bifunctional cellulose derivatives for the removal of heavy-metal ions and phenols: Synthesis and adsorption studies
In this article, we report a study of the design and synthesis of a bifunctional cellulose derivative on the removal of phenols and heavy-metal ions in wastewater treatment. A radical polymerization was performed in an ionic liquid, 1-allyl-3-methylimidazolium chloride, to graft two monomers, butyl methacrylate and 4-vinyl pyridine, on the backbone of cellulose. The effects of the five...
