Outline of Final Research Achievements

The purpose of this research is to find new Preyssler-type phosphotungstates ([P5W30O110M8n+)](15-n)-, M:encapsulated cations) by changing encapsulated cations and framework metals, and their applications as catalysis materials, conductive materials, and negative staining reagents.
I obtained following results. 1) I found a new solid state heating method to move encapsulated cations and outer counter cations, and found several new compounds. 2) I found new simple and high yield synthesis method of the Preyssler-type compounds. 3) I found that the new compounds are applicable to cataysis materials, proton-conducting materials, and memory materials. 4) I found new polymer materials which can support phosphotungstic acids.

Academic Significance and Societal Importance of the Research Achievements

リンとタングステンという元素を含む新しい酸化物分子の合成方法を見出しました。得られた新しい化合物は様々な分析手法で確認しました。また、得られた新しい化合物が、触媒材料、プロトン伝導材料およびメモリー材料として優れた性質を示すことも見出しました。これらの成果は、これまでに知られていなかった新しい材料を発見するのみならず、社会の役に立つ材料の開発に役立ちます。
