Research topics: Development of functional superatoms based on spin-spin interactions

Keyword

Summary: Atomically precise metal nanoclusters (NCs) exhibit unique electronic structures characterized by discrete energy levels similar to those of atoms and molecules. The stabilized “magic number” NCs possess characteristic electronic states known as "superatomic orbitals" (1S, 1P, 1D...), which resemble the shapes of atomic s, p, and d orbitals. Understanding these superatomic orbitals is essential for developing effective strategies to control the properties of superatoms. In this study, we aim to unveil the orbital interaction between superatomic and molecular orbitals through the spin communication with a radical ligand.

I have previously conducted research on photochromic molecules that generate radical species upon light irradiation. Since 2023, I have been pursuing a new research direction that integrates photochemistry, spin chemistry, and metal cluster (superatom) chemistry to develop novel photoresponsive functional materials. The goal of this study is to create photochemical function based on a new electronic state of superatom by spin interactions with organic radicals. With the support of this grant, I will further advance this research and promote the development of new photoresponsive functional materials based on photochemistry and molecular chemistry.
