Outline of Final Research Achievements

In the aim of exploration of superelasticity in metal-complex crystals, synthetic study on the metallic complex capable of exhibiting superelasticity under the single-crystal state. Superelasticity has not been known other than the special kind of metal alloys including Ti-Ni.
As a result, superelasticity and ferroelasticity (which is strongly related to superelasticity) were confirmed in the crystals of an organometallic compound as well as pure organic compounds analogous to ligands for metal complexes.

Academic Significance and Societal Importance of the Research Achievements

“超弾性”とは、塑性変形した固体が自発的に形状回復する特性であり、金属材料学が扱う合金等の特性とされてきた。2014年に有機物分子の単結晶における超弾性現象を発見していたが、本研究はさらに遷移金属を中心金属として導入可能な配位化合物での超弾性特性を探索するもので、新しい力学特性である超弾性を持つ機能性錯体での材料開発に貢献できる成果である。
