■ 講演内容：To advance the application of nanoclusters in chiral catalysis, we aim to understand and precisely tune their catalytic properties at the atomic level through ligand engineering and chiral spectroscopic techniques. Recently, we achieved a high-yield enantiopure synthesis of chiral nanoclusters with novel ligands, exhibiting enhanced chiral properties and remarkable stability under harsher conditions. Notably, we demonstrated enantiopure, chiral, and highly stable gold nanoclusters, including the observation of ‘super’ chirality in Au144, unveiling the intricate interplay between hierarchical chirality in ligands and cluster structure. These findings highlight the critical role of ligands in modulating the structural, catalytic, and chiral properties of gold nanoclusters, paving the way for the design of advanced materials with tailored functionalities.
