Abstract

Two types of 4- and 9-metal lanthanide-based nanoclusters [Ln2Zn2(L1)2(OAc)6] (Ln = Yb (1) and Er (2)) and [Yb9L2(L3)2(OAc)15(OH)8(H2O)2(DMF)] (3) were constructed using two Schiff base ligands that have long backbones with two and three phenyl groups. The molecular sizes of 1–2 and 3 are about 7 × 10 × 23 Å and 11 × 17 × 22 Å, respectively. These clusters exhibit typical NIR luminescence of lanthanide ions. Interestingly, 3 exhibits luminescent sensing of metal ions and exhibits high sensitivities towards Cd2+ and Co2+ ions at the ppm level.
