继续我们对高核度金属配合物的合成和表征的研究，2我们制备了发光和氧化还原活性的十三核Ru(II)-多吡啶超分子物种Ru{(#t-2，3-DPP)Ru(Bpy)(#i-2，3-DPP)Ru-[^-2，3-DPP)Ru(Bpy)2)326+(1)，如图1所示(2，3-DPP=2，3-双(2-吡啶)吡嗪；BPY=2，2‘-联吡啶)。3用图2所示的“络合物为配体，络合物为金属”的合成策略合成了新型的十三核物种1，即通过反应一个Ru[(/t-2，3-DPP)Ru(Bpy)(2，3-DPP)]38+核(2)，2d含有三个可起配体作用的自由螯合中心，其中三个Ru-[(/t-2，3-DPP)Ru(Bpy)2]2Cl24+单元(3)，2f容易含有
Continuing our studies on the synthesis and characterization of metal complexes of high nuclearity, 2 we have prepared the luminescent and redox-active tridecanuclear Ru (II)-polypyridine supramolecular species Ru {(# t-2, 3-dpp) Ru (bpy)(# i-2, 3-dpp) Ru-[^-2, 3-dpp) Ru (bpy) 2] 2) 326+(1) schematically represented in Figure 1 (2, 3-dpp= 2, 3-bis (2-pyridyl) pyrazine; bpy= 2, 2'-bipyridine). 3The novel tridecanuclear species 1 has been obtained by using the “complexes as ligand and complexes as metals” synthetic strategy illustrated in Figure 2, ie, by reacting a Ru [(/t-2, 3-dpp) Ru (bpy)(2, 3-dpp)] 38+ core (2), 2d which contains three free chelating sites that can play the role of ligands, with three Ru-[(/t-2, 3-dpp) Ru (bpy) 2] 2Cl24+ units (3), 2f which contain easily
