Surfactant-encapsulated polyoxometalate complexes are used as cluster suprasurfactants to transfer reduced graphene oxide (RGO) nanosheets from water to low polar organic solvents, which realizes the single-layer dispersion and the cluster-functionalization of RGO in one step.
The introduction of polyoxometalate type Preyssler nanoparticles at the surface cationic bis-porphyrin copolymer induces great enhancement photocurrent generation.
Polyoxometalates (POMs) can act as unique reservoirs for multiple electron transfers. As POMs display only weak absorption in the visible spectrum, they be associated with chromophores such porphyrins and porphyrin antennae. In this Minireview, research dedicated to combination of polyoxometalates is put context state art identifying challenges addressed optimization hybrid materials applicatio...
A new type of organic-inorganic hybrid supramolecular polymer has been prepared by using the base group modified polyoxometalate clusters as monomers, where the hydrogen bonds between the complementary base pairs act as the driving force.
We report ac susceptibility and continuous wave and pulsed EPR experiments performed on GdW10 and GdW30 polyoxometalate clusters, in which a Gd3+ ion is coordinated to different polyoxometalate moieties. Despite the isotropic character of gadolinium as a free ion, these molecules show slow magnetic relaxation at very low temperatures, characteristic of single molecule magnets. For T≲200 mK, th...
The coupling of a cationic dithienylethene and polyoxometalate in the first crystallized supramolecular assembly improves photoswitching organic molecule solid state.
in this paper, we have described the size-controlled synthesis of gold nanoparticles based on the reduction of au3+ (haucl4 ) using molybdophosphoric acid (h3[pmo12o40 ], hpmo) under uv-irradiation. in the process, hpmo plays the role of photocatalyst, reducing agent and stabilizer and propan-2-ol acts as a sacrificial agent. this method allows the synthesis of uniform hexagonal nanoparticles w...
