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 ...

Polyoxometalate functionalized architectures

Coordination Chemistry Reviews, 2020
Abstract Polyoxometalates (POMs) are interesting clusters that attracted great attention due to their remarkable structures and intriguing applications. The incorporation of POMs into crystalline architectures generates functional hybrid materials because such materials combine the merits of POMs and architectures together, thus deriving special ...
