Novel Metal–Organic Framework Based on Cubic and Trisoctahedral Supermolecular Building Blocks: Topological Analysis and Photoluminescent Property

Abstract Assembly of different metal-organic framework (MOF) building blocks into hybrid MOF-on-MOF heterostructures is promising in chemistry and materials science, however the development of ternary MOF-on-MOF heterostructures with controllable architectural and compositional complexity is challenging. Here we report the synthesis of three types of ternary MOF-on-MOF heterostructures via a multiple selective assembly strategy. This strategy relies on the choice of one host MOF with more than one facet that can arrange the growth of a guest MOF, where the arrangement is site-selective without homogenous growth of guest MOF or homogenous coating of guest on host MOF. The growth of guest MOF on a selected site of host MOF in each step provides the opportunity to further vary the combinations of arrangements in multiple steps, leading to ternary MOF-on-MOF heterostructures with tunable complexity. The developed strategy paves the way towards the rational design of intricate and unprecedented MOF-based superstructures for various applications.

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.

Organic Framework

A chiral metal-organic framework formulated as [Zn3(L-TMTA)2(4,4′-bpy)4]·24H2O (1) was prepared from the reaction of Zn(NO3)2·6H2O with trimesoyltri(L-alanine) (L-TMTAH3) in the presence of 4,4′-bipyridine (4,4′-bpy). Compound 1 features linear trinuclear secondary building blocks [Zn3(syn-syn-COO)2(μ2,η3-COO)2]2+. Each linear trinuclear secondary building block is further linked to another eight ones around it by four L-TMTA3– ligands and eight 4,4′-bpy ligands, leading to the construction of a uninodal three-dimensional framework with triangular prism-like one-dimensional channels. Dehydrated compound 1 displays remarkable adsorption selectivity on CO2 and water vapour over N2 gas.
