Outline of Research at the Start

本研究では、三回対称構造を有する安定有機ラジカルを用いてグラフェン様の二次元ハニカムスピン構造を形成し、その辺の中心に様々な磁気的性質(スピン多重度、異方性)を有する金属イオンを導入する。グラフェンでは実現困難なスピン構造とラジカルと磁性金属イオン間の有効な磁気相互作用に基づく磁気特性を有するヘテロスピンハニカムナノシート物質を多様に創製する。ナノシートの単層を得る手法の確立に注力し、単層磁性ナノシートの研究分野に革新的な発展をもたらす物質群の創製に挑戦する。

Outline of Final Research Achievements

A triangular-shaped radical possessing high photostability and luminescence properties was developed. The combination of the radical and metal complex units afforded novel organic-inorganic hybrid materials with two-dimensional honeycomb lattice structures. These materials are rare examples demonstrating both magnetic and photoemission properties. Developing a variety of such materials would surely be an important step toward realization of next-generation devices.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発された物質及び物質開拓法により、特異な機能を示し得るとして知られるハニカム構造物質の多種多様な創製が可能となった。これにより機能材料の基礎物性科学ならびにデバイス応用科学においてあらたな方向への展開が期待される。本研究結果は、基礎学術ならびに応用開発の両方の発展に貢献する重要な成果である。
