Outline of Research at the Start

本研究では、時間分解電子スピン共鳴法をベースに世界最高性能の空間分解能を持つ中間体構造解析の画期的ツールとして独自に開発してきた「電子スピン分極イメージング法」を主たる手法とし、時々刻々と変化する多重励起子の高スピン・低スピン各状態や光電荷分離状態の立体配置とその分子運動効果をナノ秒領域の三次元動画 (映像化)として実験的に特徴づける。結晶性と非晶性を併せ持つ有機エレクトロニクス薄膜のエントロピー効果と分子運動による電子的効果を用いるデバイス効率飛躍的向上化の知的基盤を獲得し、有機薄膜太陽電池開発で課題となっている超高効率化への指針を提示する。

Outline of Final Research Achievements

We visualized movies of the 3D views of transient species during photoinduced singlet-fission and electron transfer process by using time-resolved electron paramagnetic resonance method. We clarified that terahertz conformational motions play a role on generating quintet multiexciton and exciton dissociation by mapping anisotropy of the electron spin polarization generated in the triplet pairs and in the radical pairs. We combined microscopic and spectroscopic methods to elucidate the origins of charge-generation and recombination in organic solar cells to identify controlled lattice motion for improving the organic photovoltaic performance. Overall, the above phonon effects are concluded to be useful for several light energy conversions including the organic light-emitting diodes to enhance the radiative recombination from separated electron-hole pairs

Academic Significance and Societal Importance of the Research Achievements

有機太陽電池材料の薄膜では、結晶性と非晶性を併せ持つ極めて不均一な分子集合体で構成され、X線結晶構造解析法で分子構造の全体像を知ることは極めて困難であった。本研究は、励起子や光電荷分離の各ステージの異なる空間領域で生成する中間体を同定するだけでなく、各中間体の立体的位置、距離、分子配向、運動性および、軌道の重なりや広がりの性質新しい磁気イメージング法に基づき非破壊的に調べた。国内外で従来全く考えられていなかった発想で、非晶質系や不均一系でも高い空間分解能を持ったナノ秒時間分解構造解析を可能にしたものであり、今後の超高効率デバイス分子開発や分子設計で大きな役割を果たすことでがきる。
