摘要：

Two 12-metal Zn-Ln nanoclusters [Zn(8)Ln(4)L(8)(OAc)(8)](OH)(4) (Ln = Sm (1) and Nd (2)) were prepared using a long-chain Schiff base ligand with a flexible (CH2)(3)O(CH2)(2)O(CH2)(3) backbone. These two Zn-Ln clusters possess interesting rectangular structures. The long-chain Schiff base ligand adopts a "linear'' configuration in the structures, resulting in the large sizes of 1 and 2 (about 9 x 19 x 28 angstrom). Chromogenic Zn/L components in the clusters can act as efficient sensitizers for lanthanide luminescence, and 1 and 2 exhibit emission from Sm3+ and Nd3+, respectively. Their visible and NIR luminescence properties were investigated.
