TL;DR: By the reaction of TBA4H4[γ-SiW10O36] (TBA = tetra-n-butylammonium) with AgOAc (OAc = acetate) using dimethylphenylsilane as a reductant in acetone, a unique polyoxometalate containing a discrete octahedrally shaped [Ag6]4+ cluster, TBA8[Ag6(γ-H2SiW 10O36)2]·5H2O, could be synthesized, and the molecular

TL;DR: In this article, a pyridyl-capped Anderson-Evans polyoxometalate was used to fabricate single-molecule junctions, using the organic termini to chemically solder a single cluster to two nanoelectrodes.
Abstract: Polyoxometalates have been proposed in the literature as nanoelectronic components, where they could offer key advantages with their structural versatility and rich electrochemistry. Apart from a few studies on their ensemble behaviour (as monolayers or thin films), this potential remains largely unexplored. We synthesised a pyridyl-capped Anderson-Evans polyoxometalate and used it to fabricate single-molecule junctions, using the organic termini to chemically "solder" a single cluster to two nanoelectrodes. Operating the device in an electrochemical environment allowed us to probe charge transport through different oxidation states of the polyoxometalate, and we report here an efficient three-state transistor behaviour. Conductance data fits a quantum tunnelling mechanism with different charge-transport probabilities through different charge states. Our results show the promise of polyoxometalates in nanoelectronics and give an insight on their single-entity electrochemical behaviour.

TL;DR: In this paper, the first three-connected, 5-fold interpenetrating network based on polyoxometalate building blocks and metal−organic frameworks is presented. But it is not a 3D network.
Abstract: The first three-connected, 5-fold interpenetrating network based on polyoxometalate building blocks and metal−organic frameworks that represents the highest degree of interpenetration presently known for 3D polyoxometalate systems is reported.

TL;DR: A three-component supramolecular hybrid system based on host-guest recognition and electrostatic interaction has been developed for a consecutive chiral transfer from an alpha-cyclodextrin to cationic dyes via the bridge of a new azobenzene-grafted Anderson-type polyoxometalate cluster.

TL;DR: The first polyoxometalate (POM)-encapsulated twenty-four-nucleus organophosphorus-copper nanocage cluster organic framework has been constructed and the resulting material exhibited highly efficient bifunctional electrochemical performance.
