| Outline of Final Research Achievements |
Organically modified polyoxometalates were prepared by hydrolyzing metal alkoxides in the presence of chelating agents like benzoylacetone (BzAc), followed by concentration and drying. The softening temperature was found to be affected by the molecular weight of the polymerized species, which are varied with the amounts of the chelating agents and of the water for hydrolysis. Structural analysis based on pair distribution function suggested that the BzAc-modified polyoxotitanates are composed of TiO6 octahedra that are liked by corner- and edge-sharing. The BzAc-modified polyoxotitanates showed glass transition in their low-temperature TMA and DSC curves, suggesting that such organically modified polyoxometalates could be a new class of glassy materials.
