| Outline of Final Research Achievements |
In order to realize π-bands in heterometallic one-dimensional chains, molybdenum and platinum dinuclear complexes were mixed to form metal-metal bonds in the π-orbitals. Although it was not succeeded in isolating one-dimensional chains where both metals were regularly aligned, we found that in the reaction the oxidation and decomposition of the molybdenum dinuclear complex produced polyoxometalate with highly oxidized metals. We have succeeded in synthesizing one- or two-dimensional mixed-valence aggregates with delocalized unpaired electrons, where both polyoxometalate and tetranuclear platinum complexes are regularly aligned.

| Academic Significance and Societal Importance of the Research Achievements |
ポリオキソメタレートは古くから知られ、固体酸触媒に使われてきた化合物であるが、骨格自体を導電物性に利用している研究はほとんどない。本研究で見出した、ポリオキソメタレートと白金四核錯体からなる混合原子価集積体は非局在化した電子を有し、比較的電気が流れやすいと考えている。この集積体は、2つの調整可能な物質を混合して得られることから、バンド構造、電荷輸送能、光吸収帯をチューニングできる化合物群といえ、太陽電池などに利用できれば、学術的・産業的にも大きな波及効果が期待される。
