Anion-Dependent Self-Assembly of Near-Infrared Luminescent 24- and 32-Metal Cd–Ln Complexes with Drum-like Architectures

Two series of 4d–4f clusters [Ln8Cd24L12­(OAc)48] and [Ln6Cd18L9Cl8(10)­(OAc)28(26)] (Ln = Nd, Gd, Er, and Yb) with novel drum-like structures were prepared using a flexible Schiff base ligand. Their NIR luminescence properties were determined.采用柔性的席夫碱配体，成功制备了两种新型的4d-4f簇系列化合物[Ln8Cd24L12(OAc)48]和[Ln6Cd18L9Cl8(10)(OAc)28(26)]（其中Ln代表Nd、Gd、Er和Yb），它们具有独特的鼓状结构。对这些化合物的近红外发光特性进行了测定。
