AI Summary

Researchers demonstrated that racemic carbon‑centered gold(I)–silver(I) clusters, which are highly luminescent but lack circular polarization, can be converted into bright circularly polarized light (CPL) emitters through enantioresolution. By treating the clusters with chiral oxygen‑donor ligands, the team separated the material into mirror‑image enantiomers that preserve strong photoluminescence while acquiring significant luminescence dissymmetry. The work, reported in Advanced Optical Materials, shows that chiral donor ligands can resolve racemic metal clusters without sacrificing efficiency, offering a pathway to bright CPL sources for optical applications.
