Outline of Final Research Achievements

Based on discrete, aliphatic polyketones, novel organic materials such as light-emitting solids and metal-organic frameworks have been developed. In particular, relationships between function and structure were revealed using single crystal X-ray structures. Moreover, the boundary length between polymer and oligomer polyketones with respect to solid-state alignment was found to exist around 4~6-mer region. Aliphatic polyketones provided a new research target in structural organic chemistry and materials chemistry because they have both structural flexibility and diversity in chemical reactions.

Academic Significance and Societal Importance of the Research Achievements

構造と機能の相関関係は、有機機能性材料を開発する上で重要な要素である。しかし、現在の材料開発では機能の創出が優先され、構造に基づく機能発現原理の解明が後回しにされている状況が多い。そこには、分子が複雑で巨大になるほど構造解析が難しくなってしまうという問題がある。本研究では、様々な構造を誘起できる柔軟な脂肪族ポリケトンの単結晶X線構造解析を主体として、構造とその化合物が示す機能の関係を解明した。これにより、構造の制御法と得られる機能を広く解明することができた。
