Outline of Final Research Achievements

Coordination polymers containing sulfur coordination atoms, namely S-CPs, have attracted much attention due to their excellent carrier mobility. However, their magnetic properties have been unexplored. In this study, by utilizing materials informatics, S-CPs composed of Mn(II) and Co(II) ions were synthesized. Physical property characterization revealed that the series of compounds exhibit both semiconductive properties arising metal-sulfur bond and magnetic properties occurring from metal centers. The insights obtained through this study undoubtedly lead to the development of new spintronics materials based on coordination polymers.

Academic Significance and Societal Importance of the Research Achievements

スピントロニクスは、元来電子が持つ「電荷」と「スピン」の両方を利用する研究領域であり、従来までの「電荷」の性質のみを利用するエレクトロニクスに代わる新しい技術として注目を集める。一方で、電荷の性質とスピンの性質が共存・相関したスピントロニクス材料の報告は限定的であり、更なる材料探索・開発が求められる。本研究を通じて得られた知見は、配位高分子を物質基盤としたスピントロニクス材料の開発に向けた新しい設計指針を与え、錯体化学領域から材料科学領域に至るまで極めて大きなインパクトを与えると期待される。
