Two types of 4- and 9-metal lanthanide-based nanoclusters [Ln 2 Zn 2 (L 1 ) 2 (OAc) 6 ] (Ln = Yb ( 1 ) and Er ( 2 )) and [Yb 9 L 2 (L 3 ) 2 (OAc) 15 (OH) 8 (H 2 O) 2 (DMF)] ( 3 ) were constructed using two Schiff base ligands that have long backbones with two and three phenyl groups. The molecular s...

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,

exhibits luminescent sensing of metal ions and exhibits high sensitivities towards Cd

and Co
2+
ions at the ppm level.
Two types of 4- and 9-metal lanthanide-based nanoclusters (Ln = Yb(

) and Er(

)) were constructed and the 9-metal Yb(

) cluster shows interesting luminescent sensing of metal ions and exhibits high sensitivity to Cd
2+
and Co

at ppm level. |
