Fluorescent nano-/microrods of the polyoxometalate (POM) K4H[Eu(α-SiW11O39)(H2O)2] · 17H2O were obtained in aqueous solution by a conventional synthesis method. The nano-/microrods have been characterized by elemental analysis and FT-IR, UV/Vis, and TG-DTA data, and their morphology was examined by ESEM-FEG, showing that the average ratio of diameter to length is 1 : 20. The obtained nano-/micr...

A novel route to facilitate the degradation of phenol is reported. This new approach is based on a micellar polyoxometalate (POM) catalytic system. The micellar POM catalyst could promote phenol molecules' degradation into a simple inorganic compound such as CO2 using only air as an oxidant under room conditions. The results of the recycling experiment suggests that the micellar POMs may be use...

A new paradodecatungstate-B compound, [{Co(H2O)4}4(H4W12O42)]·10H2O (1) of the polyoxometalate series has been synthesized and characterized by elemental analysis, IR and UV spectroscopy, TG analysis, and single-crystal X-ray diffraction. Compound 1 exhibits a unique 8connected three-dimensional (3D) framework with a (42 · 820 · 126) topology. Moreover, 1 displays antiferromagnetic interactions...

The unsymmetrical Mn-Anderson polyoxometalate cluster, [N(C4H9)4]3[MnMo6O18(C4H6O3NO2)(C4H6O3NH2)] (1; N(C4H9)4(+) = TBA(+)), has been prepared and characterized by X-ray crystallography and electrospray ionization mass spectrometry (ESI-MS). Covalent functionalization of compound 1 leads to the controlled assemblies of unsymmetrical alkoxopolyoxometalate clusters of compounds 2-5, which can be...

A new kind of organic-inorganic hybrid complexes based on polyoxometalate were synthesized through symmetrically grafting two adeninyl groups onto Anderson-type MnMo(6) clusters and encapsulating the clusters by organic surfactants. The resultant complexes exhibited thermal-induced dynamic self-assembly behaviors which greatly depended on the ambient temperature and the chain length of cationic...
