Key facts
- Successful Development of Asymmetric Alloying Method for Carbon-Centered Gold(I) Ion Clusters: Chiral Alloy Clusters Emitting Light in the Red to Near-Infrared Regions
- A collaborative research team from Tokyo University of Science, Institute for Molecular Science, and Fuzhou University successfully developed an "asymmetric alloying" method. By adding silver salts and a homochiral carboxylic acid to a carbon-centered gold(I) ion cluster, they synthesized optically pure chiral carbon-centered gold(I)-silver(I) alloy clusters. These clusters exhibit long-lived phosphorescence and circularly polarized luminescence in the red to near-infrared regions, showing promise for applications in chiral luminescent nanomaterials and optical functional materials.
