A luminescent multilayer film has been fabricated from the polyoxometalate anion α[PMo12O40]3− (α-PMo12) and the cation Fuchsin Basic (FB) through an electrostatic layer-by-layer (LbL) self-assembly method and characterized by UV/Vis spectra, atomic force microscopy and X-ray photoelectron spectra. The fluorescence properties of the LbL film have also been investigated. Cyclic voltammetry measu...

Films based on electrostatic interactions between tetracationic porphyrin and Dawson type polyoxometalate are formed by the so called layer-by-layer method. Their photovoltaic performances are investigated by photocurrent transient measurements which showed significant photocurrent response.

Polyoxometalates can serve as active components to induce and modulate the micellization behavior of polystyrene-block-poly(4-vinylpyridine).

The reaction of Cl(3)Sn(CH(2))(2)COOCH(3), [H(2)P(2)W(12)O(48)](12-) and WO(4)(2-) in acetate buffer solution led to the hydrolysis of estertin into a carboxyethyltin group and the assembly of a new tetra(organotin)-decorated boat-like polyoxometalate.

a new hybrid nanomaterial was developed by immobilization of phosphomolybdate anions on the surface of modified magnetite nanoparticles with quaternary phosphonium cations. silica coated magnetic nanoparticles supported phosphonium cations, ph3p+-scmnps, were prepared by covalent attachment of chloropropylsilyl groups on the surface of silica coated magnetite nanoparticles and next reaction wit...

We have fabricated a novel organic/inorganic hybrid material consisting of multifunctional surfactant-encapsulated polyoxometalloeuropate which functions as a luminescent logic gate with dual output operated by light and metal ion as inputs.

"Out-of-pocket" association of Ag(+) to the tetradentate defect site of mono-vacant Keggin and Wells-Dawson polyoxometalate (POM) cluster-anions is used to direct the formation of water-soluble AgCl nanocubes.

The pH-controlled assembly/disassembly of a nanoscale {P4W52O178}24- cluster at pH 2 to a {P4W44O152}20- cluster at pH 3-5 via a {P3W39O134}19- cluster species at pH 2-3 to finally give {P2W19O69(OH2)}14- at pH 6 is reported. This process can be traced in the solid state crystallographically and in solution using dynamic light scattering studies.

A Cu(II)-phenanthroline connected Strandberg-type polyoxometalate based proton conducting MOF, Cu(3)Mo(5)P(2), that contains one dimensional parallel water channels has been reported. Cu(3)Mo(5)P(2) shows proton conduction at room temperature as well as elevated temperature.

The mixed-valent cerium(III/IV) oxide clusters {Ce(10)} and {Ce(22)}, derived from condensation reactions of cerium carboxylate coordination polymers, exhibit molecular growth tendencies similar to those of 'classical' group V and VI polyoxometalates, but with increasing nuclearity approach the structure of the parental oxide, CeO(2).
