Organic Framework

Pillared paddle-wheel-based metal-organic framework (MOF) materials are an attractive target as they offer a reliable method for constructing well-defined, multifunctional materials. A drawback of these materials, which has limited their application, is their tendency to form catenated frameworks with little accessible volume. To eliminate this disadvantage, it is necessary to investigate strategies for constructing non-catenated pillared paddle-wheel MOFs. Hydrogen-bonding substituents on linkers have been postulated to prevent catenation in certain frameworks and, in this work, we present a new MOF to further bolster this theory. Using 2,2′-diamino-[1,1′-biphenyl]-4,4′-dicarboxylic acid, BPDC-(NH2)2, linkers and dipyridyl glycol, DPG, pillars, we assembled a MOF with pcu topology. The new material is non-catenated, exhibiting large accessible pores and low density. To the best of our knowledge, this material constitutes the pcu framework with the largest pore volume and lowest density. We attribute the lack of catenation to the presence of H-bonding substituents on both linkers.

Organic Framework

A metal–organic framework with a novel topology, poly[sesqui(μ2-4,4′-bipyridine)bis(dimethylformamide)bis(μ4-4,4′,4′′-nitrilotribenzoato)trizinc(II)], [Zn3(C21H12NO6)2(C10H8N2)1.5(C3H7NO)2]n, was obtained by the solvothermal method using 4,4′,4′′-nitrilotribenzoic acid and 4,4′-bipyridine (bipy). The structure, determined by single-crystal X-ray diffraction analysis, possesses three kinds of crystallographically independent ZnIIcations, as well as binuclear Zn2(COO)4(bipy)2paddle-wheel clusters, and can be reduced to a novel topology of a (3,3,6)-connected 3-nodal net, with the Schläfli symbol {5.62}4{52.6}4{58.87} according to the topological analysis.
