Three pairs of chiral Ln-Ag(I) clusters d/l-Ln3Ag5 with C3 symmetry were prepared by d/l-penicillamine as multidentate ligand bridged Ln3+ and Ag(I) ions. The chiral ligand induced the molecular cluster to be chiral, and the CD spectra of the chiral compounds d/l-Ln3Ag5 were slightly blue-shifted due to the lanthanide contraction. The studies of optical properties indicated that tunable photoluminescence from {AgS}-to-Ln3+ was achieved by introducing Ln3+ ions with different emission bands or regulating various excitation light.
