A Metal-Organic Framework of Organic Vertices and Polyoxometalate Linkers as a Solid-State Electrolyte.

Journal of the American Chemical Society, 2019
A new three-dimensional metal-organic framework (MOF) was synthesized by linking ditopic amino functionalized polyoxometalate [N(C4H9)4]3[MnMo6O18{(OCH2)3CNH2}2] with 4-connected tetrahedral tetrakis(4-formylphenyl)methane building units through imine ...

A polyoxometalate@covalent triazine framework as a robust electrocatalyst for selective benzyl alcohol oxidation coupled with hydrogen production

, 2021
Electrocatalytic oxidation has been proven as a sustainable and promising alternative to traditional chemical transformation, but its further development is limited by the use of noble-metal electrocatalysts.

Iron Polyoxometalate Single‐Molecule Magnets

Angewandte Chemie, 2009
AbstractWolframate mit Eisenfüllung: Zwei neue Polyoxowolframate mit paramagnetischen Eisen(III)‐Ionen (siehe Struktur, W blau, Fe gelb, O rot) haben Grundzustände mit S=15/2 und S=5. Beide Verbindungen sind Einzelmolekülmagnete, und die Hexaeisen‐Spezies zeigt eine starke Hysterese (siehe Diagramm) sowie Quantentunneleffekte bei tiefen Temperaturen ...

The fascinating polyoxometalates

ChemTexts, 2021
After touching the history of polyoxometalate (POM) chemistry, the basics of isopolyoxometalates (IPOM) and heteropolyoxometalates (HPOM) are discussed. The main focus is placed on molybdenum- and tungsten-containing IPOM and HPOM. The HPOM are presented based on the coordination of the ‘hetero’atom: tetrahedral (Keggin and Wells–Dawson structures ...

Towards Polyoxometalate‐Integrated Nanosystems

Chemistry – A European Journal, 2006
AbstractPolyoxometalates represent a diverse range of molecular clusters with an almost unmatched range of physical properties and the ability to form structures that can bridge several length scales. The new building block principles that have been discovered are beginning to allow the design of complex clusters with desired properties and structures;

Noble Metals in Polyoxometalates

Angewandte Chemie International Edition, 2012
AbstractPolyoxometalates containing noble metal ions, such as ruthenium, osmium, rhodium, palladium, platinum, silver and gold, are a structurally diverse class of compounds. They include both classical heteropolyanions (vanadates, molybdates, tungstates) in which noble metals are present as heteroatoms, as well as the recently discovered class of ...

Targeted Delivery of Polyoxometalate Nanocomposites

Small, 2011
AbstractPolyoxometalate/carboxymethyl chitosan nanocomposites with an average diameter of 130 nm are synthesized and labeled with fluorescein isothiocyanate (FITC) for a combined drug‐carrier and cellular‐monitoring approach. [Eu(β2‐SiW11O39)2]13−/CMC nanospheres as a representative example do not display cytotoxicity for POM concentrations up to 2 mg ...
