Metal-controlled assembly results in a series of lanthanide clusters with the formula of Ln(5)(DBM)(10)(OH)(5) x n(solvent) (DBM = dibenzoylmethanido; Ln = Nd (1), Gd (2), Er (3), and Yb (4); solvent = CH(3)CN or toluene). These pentanuclear clusters with square-pyramidal core structures have been characterized by X-ray diffraction analysis. Clusters 1, 3, and 4 show typical near-infrared (NIR) luminescence upon excitation at 350 nm, which represents the first examples of pentanuclear lanthanide clusters with sensitized NIR emission.
金属控制组装得到一系列具有通式 Ln(5)(DBM)(10)(OH)(5) x n(solvent) 的镧系元素簇(DBM = 二苯甲酰甲烷;Ln = Nd(1)、Gd(2)、Er(3)和 Yb(4);溶剂 = CH(3)CN 或甲苯)。这些具有四方锥核结构的五核簇已通过 X 射线衍射分析进行了表征。簇 1、3 和 4 在 350nm 激发下表现出典型的近红外(NIR)发光,这代表了首例具有敏化 NIR 发射的五核镧系元素簇。
