Outline of Final Research Achievements

We have promoted collaborative research on chiral nanomaterials with researchers between Kyoto University, University of Hyogo, and at University of Bordeaux. In particular, we have developed materials such as metal nanohelices and helical nanopores on the surface of semiconductors based on self-organization such as spatiotemporal pattern formation, and have evaluated their properties. Specifically, we have conducted three projects: research on the self-organization of the electrodeposition of metal nanohelices using porous alumina as a template, measurement of photoluminescence from helical Si nanopores formed by Pt catalyst, and generation and readout of time-varying circularly polarized light spectrum patterns.

Academic Significance and Societal Importance of the Research Achievements

本国際共同研究プロジェクトでは、時空間パターン形成化学とキラル分子化学の境界領域の開拓を目指し、京都大学を中心とする国内グループとボルドー大学（フランス）の研究者との国際連携を推進した。コロナ禍の後、研究代表者や研究分担者の若手研究者、ならびに大学院生がボルドー大学を訪問し、実際に実験を進めることで特に若手研究者のエンカレッジにつながり、国際共著論文を複数発表するなど、高い評価を得た。
