Outline of Final Research Achievements

We synthesized light-harvesting antennas consisting of cyclic oligosaccharide with high light absorption property and constructed supramolecular complexes with photo-functional molecules. In this study, the unique photophysical properties of the light-harvesting antennas were clarified.

Academic Significance and Societal Importance of the Research Achievements

我々は、天然の光合成によって地球に蓄えられたエネルギーを消費して経済活動を行っている。太陽光エネルギーを化学や電気エネルギーへと変換可能なシステムの研究・開発は、今後も欠かすことができない。本研究によって創出した光捕集アンテナ分子は、光エネルギーの高効率変換へと繋がり、現状の化石燃料に依存した社会からの脱却を可能にすることが期待される。
