Polyoxometalates (POMs) have been a popular motif in crystal engineering. In this work, seven ionic crystals based on Keggin- or Dawson-type POMs and mononuclear Bi(III) complexes were synthesized. The center exhibited triangular dodecahedron, square antiprism, pseudo-cubic eight-coordination geometries, with DMSO DMF as ligands. showed polymorphic transformations, high proton conductivities de...

Polyoxometalates (POMs) are discrete polynuclear metal-oxo anions with a fascinating variety of structures and unique chemical and physical properties. Their application in various fields is well covered in the literature, however little information about their usage in protein crystallization is available. This review summarizes the impact of the vast class of POMs on the formation of protein ...

Polyoxometalates (POMs) equipped with vanadium centers offer outstanding opportunities for the development of switchable molecularly functionalized surfaces non-binary, beyond-CMOS memory chips. In article number 2200461, Maria Glöß, Silvia Karthäuser, Kirill Yu. Monakhov, and co-workers report a room-temperature, multistate resistive switch based on V3-substituted Wells-Dawson-type POM structu...

High efficacy and low toxicity are critical for cancer treatment. Polyoxometalates (POMs) have been reported as potential candidates for cancer therapy. On accounts of the slow clearance of POMs, leading to long-term toxicity, the clinical application of POMs in cancer treatment is restricted. To address this problem, a degradable organoimido derivative of hexamolybdate is developed by modifyin...

The chemistry of polyoxometalates has been reviewed extensively. Much useful information about the synthesis, study of structures and various applications of heteropoly acids and their salts have been reported in the literature. Thus, POMs inorganic complexes composed of transitional metals mainly Mo, W and V. The present review gives an introduction into the chemistry of these compounds and ov...

Prions are composed solely of an alternatively folded isoform of the prion protein (PrP), designated PrP(Sc). N-terminally truncated PrP(Sc), denoted PrP 27-30, retains infectivity and polymerizes into rods with the ultrastructural and tinctorial properties of amyloid. We report here that some polyoxometalates (POMs) favor polymerization of PrP 27-30 into prion rods, whereas other POMs promote ...

Zwitterions and polyoxometalates (POMs) are two kinds of functional moieties with very different properties for applications in different fields. We have developed an effective strategy to successfully immobilize these two different moieties into the frameworks of porous hybrid materials, in which the POM units act as templates and photoactive moieties. These hybrid materials demonstrate remark...

Polyoxometalates (POMs) are polyatomic ions with closed three-dimensional frameworks. Their unique structure contains a large number of redox active sites, making them promising electrocatalysts for electrochemical energy conversion and storage applications. Thus, this paper presents an overview the use POMs as devices, such batteries, supercapacitors, fuel cells, or water electrolyzers. A disc...

Polyoxometalates (POMs), a type of giant transition metal oxide clusters on the nanoscale, are emerging as useful materials with unique catalytic, electrooptical, and biological properties. Lanthanide-containing POMs elements show excellent photoluminescent properties with narrow emission bands, large Stokes shift, long lifetime, and tunable emission, i.e., their long emission timescale (microt...

We report the preparation of solution-derived metal oxide nanocomposite films by combining polyoxometalates (POMs) and colloidal oxide nanocrystals. Polyniobates and vanadates were combined with Sn-doped In2O3 (ITO) nanocrystals leading to Nb2O5–ITO, V2O5–ITO and VO2–ITO nanocomposite films. Compared to other solution-phase methodologies, this approach offers excellent control of the nanoinclus...
