Self-assembly of NIR luminescent 30-metal drum-like and 12-metal rectangular d–f nanoclusters with long-chain Schiff base ligands†
Abstract
Two classes of heterobimetallic d–f nanoclusters [Ln6Cd24(L1)11(OAc)43(OH)] and [Ln4Zn8(L2)2(OAc)20(OH)4] (Ln = Nd and Yb) were prepared using flexible long-chain Schiff base ligands which have (CH2)6 backbones. Their NIR luminescence properties were determined.
