Achiral-Core-Metal Change in Isomorphic Enantiomeric AgAg and AuAg Clusters Triggers Circularly Polarized Phosphorescence.

Understanding how the chiral or achiral section in chiral nanostructures contributes to circularly polarized light emission (CPLE) at the atomic level is of fundamental importance. Here, we report two pairs of atomically precise enantiomers of homosilver () and heterometal () clusters. The geometrical chirality of arises from the chiral ligand and interface consisting of positive moieties of Ag(/-PS).
