研究内容 |
本新学術領域研究では、アシンメトリック空間において力学的な力で分子を励起することで生じる化学反応を検討する。物質に力学的な力を与えた時に励起状態が形成し、発光が生じる現象(トリボルミネッセンス)が古くから知られている。このような性質を示す化合物の一つに希土類錯体がある。この希土類錯体は7配位-12配位の高配位数を有するため、多種の配位子が希土類イオン周りに密に集積するという特徴も示す。本研究では希土類錯体にi)励起状態形成に伴い化学反応が生じる分子骨格、ii)特徴的なアシンメトリック空間を形成する配位子(ex.キラル配位子)を導入する。この希土類錯体内で励起状態を介した化学反応を力学的な力で誘起させ、その構造変化・光物性変化を検討していく。
