structurally revealed by X-ray crystallographic analysis. The dimerized (1) and trimerized (2) macrocycles of binary molecules based on adamantane with acetylenic aromatic ring moieties were designed and effectively synthesized. Similarly, a cryptand-like macrobicyclic cage (3) was constructed from a trisubstituted adamantane derivative. Single-crystal X-ray analysis revealed that both cyclic compounds have
已经开发出了基于金刚烷的大环化合物和具有芳族环部分的笼,并通过X射线晶体学分析揭示了其结构。设计并有效合成了基于金刚烷和乙炔芳环部分的二元分子的二聚化(1)和三聚化(2)大环。类似地,由三取代的金刚烷衍生物构造了类似穴状的大双环笼(3)。X射线单晶分析表明,两种环状化合物均具有几乎为矩形的形状,空腔中有或没有溶剂分子。大双环笼具有内部空间,并通过CH···π相互作用容纳氯仿分子。大环化合物和笼型封装1,3,5-三硝基苯(4)以平行方式通过电荷转移相互作用以一对一的形式作为贫电子客体,并显示了由两种不同类型组成的分子网络(例如柱,管,2D层和3D网络)的形成固态的非共价相互作用。
