Outline of Final Research Achievements

In this study, the chain dynamics and the carrier properties for various functional polymers were examined. The carrier properties in a typical semiconducting polymer of poly(3-hexylthiophene) were closely related to the relaxation temperature for the twisting motion of thiophene rings in a crystalline phase. Also, we directly examined the energy state of the cured epoxy compound near the copper interface through the behavior of the excited species.

Academic Significance and Societal Importance of the Research Achievements

本研究成果の学術的意義は、従来、主に分子構造と機能の関係が着目されてきた機能性高分子に構造・物性の観点から機能発現の要因を探る方法論を与えた点にある。これは、機能性高分子の研究開発サイクルの加速化に貢献するものと期待される。また、励起子をプローブにした相互作用の評価法は、埋もれた界面の新しい解析方法を提案するとともに、界面の理解を促進させるものである。
