| Outline of Final Research Achievements |
Luminescent lanthanide complexes are organic-inorganic hybrid material composed of lanthanide ion and organic compounds, which have attracted considerable attention because of their emissions with high color purity. We produced results of luminescent Eu complexes with supramolecular-type interactions as follows. (1) We synthesized luminescent Eu complex with high brightness, high thermostability, and high solubility in an organic solvent.(2)We obtained design guideline for Eu complexes with excellent circularly polarized emission properties. (3)We constructed analysis method of 4f-5d transitions of lanthanide complexes.

| Academic Significance and Societal Importance of the Research Achievements |
現在、光産業の中で特に発光体の開発が重要とされている。発光性希土類錯体とは希土類イオンと有機分子から構成される有機・無機ハイブリッド材料であり、色純度の高い発光色を示すことから注目を集めている。
本研究成果ではこのような発光性希土類錯体に対して超分子型の相互作用を利用することで従来達成されていない発光機能付与(熱耐久性と有機溶媒への溶解性の両立、青色光励起可能なEu発光体など)に成功しており、学術的な意義だけでなく産業的にも意義深い。
