以简单的双核Zn-Nd配合物[ZnNdL(H2O)(NO3)3] (1) （H2L = N,N ' -双（3-甲氧基水杨酸基）乙烯-1,2-二胺）为前体，形成四核[Zn2Nd2L2(4,4 ' -bpy)(NO3)6]·Et2O(2)和[Zn2Nd2L2(4,4 ' -bpe)]·2H2O (3) （4,4 ' -bpy = 4,4 ' -联吡啶，4,4 ' -bpe =反式-双（4-吡啶基）乙烯）配合物：选择合适的双齿连接剂可以构建具有较好发光性能的多核异质金属3d-4f席夫碱配合物，对连接剂特性的控制是调控Nd离子近红外发光性能的潜在有效途径。
With the simple dinuclear Zn–Nd complex [ZnNdL(H2O)(NO3)3] (1) (H2L = N,N′-bis(3-methoxysalicylidene)ethylene-1,2-diamine) as the precursor, tetranuclear [Zn2Nd2L2(4,4′-bpy)(NO3)6]·Et2O (2) and [Zn2Nd2L2(4,4′-bpe)]·2H2O (3) (4,4′-bpy = 4,4′-bipyridine, 4,4′-bpe = trans-bis(4-pyridyl)ethylene) complexes are formed: suitable choice of bidentate linkers could construct multinuclear heterometallic 3d–4f Schiff-base complexes with improved luminescent properties, and the controlling of linker character shows a potentially effective way to the fine-tuning properties of NIR luminescence from Nd ions.
