Outline of Research at the Start

太陽光発電や光触媒ならびに、有機発光素子の開発では近年、クリーンな有機材料を用いた超高効率光エネルギー変換系へのデバイス応用に急速な期待が高まっている。本計画では三重項-三重項消滅(TTA)による光アップコンバージョン(UC)の超高効率化を連結系一分子レベルでの分子振動によって達成させる。このための基礎研究として主に時間分解電子スピン共鳴法を用い、三重項励起子の出会いにより生成する分子内多重励起子(T1T1)のスピン変換過程による一重項励起子生成機構の詳細を明らかにする。熱活性化された特定の分子内振動による超高効率な多重励起子の五重項から一重項への変換機構を世界で初めて実証する。

Outline of Final Research Achievements

The microscopic motion of electron spins inside an organic thin-film solid capable of efficiently converting near-infrared light into visible light was investigated, and the authors succeeded for the first time in the world in capturing the highly efficient generation of short-wavelength light by the spin state change of triplet excitons formed as intermediates through rotational diffusion motion inside the solid. The model analysis of the motion of triplet exciton pairs (TT) formed during the TTA reaction revealed that the singlet exciton with luminescent properties is generated with an efficiency of 77% due to the spin multiplicity conversion, indicating that the modulation of the spin-dipole interaction by the orientation motion of the triplet exciton is responsible for the generation of short wavelength light. The modulation of the spin-dipole interaction due to the orientational motion of the triplet exciton plays an important role in the efficiency of the TTA reaction.

Academic Significance and Societal Importance of the Research Achievements

中間体として生成する三重項励起子が固体内部の回転拡散運動でスピン状態を変化させて短波長の光を高効率に生じる様子を捉えることに世界で初めて成功した。これにより、今後、高効率光エネルギー変換デバイス開発が進展し、世界的なエネルギー問題解決に貢献するとともに、人体に害のない近赤外光を光アップコンバージョンさせ利用する光線力学的ながん治療や診断など幅広い分野への展開が期待される。
