Outline of Research at the Start

本研究期間中に、前述の「空間展開された分光円偏光の同時生成」技術を確立し、これによる高速の円二色性スペクトル測定技術を実証し、さらに実際の分析や材料開発に適用して役立てることを計画している。具体的には、以下の3つの課題を実施する計画である。
・紫外-可視領域および深紫外-可視領域の空間展開された分光円偏光を生成する偏光回折素子の開発
・紫外-可視領域および深紫外-可視領域の高速円二色性スペクトルメータの開発
・高速円二色性スペクトルメータによる物質分析及び材料開発

Outline of Final Research Achievements

High-speed measurement technique of circular dichroism (CD) spectrum was proposed and demonstrated. Left and right circularly-polarized light was generated simultaneously by wavelengths, using polarization diffractive gratings. As a result, CD spectrum can be measured in a short time, which enables to acquire the temporal changes of molecules. Among these studies, we also developed some functional molecules with chirality changes based on the conformational changes. Thereby, the validity of such kind of spectroscopic analysis approach could be confirmed.

Academic Significance and Societal Importance of the Research Achievements

本研究では、キラル物質のコンフォメーション変化を逐次的に捉えることを目的に、円二色性スペクトルメータにおける、従来の時間展開型のスペクトル測定を、空間展開型のスペクトル測定に転換して、高速化することを提案し、その基本動作を実証した。このような測定技術が将来的に成熟することで、分子のコンフォメーション変化のダイナミクスを追跡可能となると期待される。これにより、例えば、タンパク質の変性が引き起こすコンフォメーション病のメカニズムの解明や治療方法の研究等に役立つと期待される。また、左右の円偏光を波長ごとに空間的に同時に展開する偏光素子を実現しており、更なる偏光応用技術等の発展につながると期待される。
