含潜在异构手性双臂配体的螺旋组装和手性聚集（Helical Assembly and Chiral Aggregations Based on Atropisomeric Molecular Clips）
晶体结构 配合物 螺旋组装 手性聚集
2010/8/18
采用具有潜在异构手性的双臂配体，双吡啶二甲基联苯-2，2′-二酰肼，合成了4个双核螺旋配合物。配体与CdI2和Cu(NO3)2反应得到双核单螺旋化合物1和2，在化合物2中，由于C-H…π和π…π的协同相互作用沿ab面形成单一手性的二维平面。双核双螺旋化合物3(Ni(Ⅱ))和4(Co(Ⅱ))中的金属中心表现相同的绝对构型，说明含异构手性的配体能够把金属中心的手性从一个中心传递到另一个中心。
