预先设计的分子“夹子”(4) 与刚性联吡啶桥连配体在丙酮/水混合物中相互作用，通过自发自组装形成矩形分子 (5-8)，分离产率为 92-97%。通过多核核磁共振和紫外可见光谱、FAB 质谱和 X 射线晶体学完成表征。这些金属大环的长度范围为 2 至 3 nm。通过非亲核抗衡离子交换进行后修饰可增强组件的结构完整性。
Interaction of a predesigned molecular "clip" (4) with rigid dipyridyl bridging ligands, in acetone/ water mixtures, leads to the formation of molecular rectangles (5-8) in 92-97% isolated yields via spontaneous self-assembly. Characterization was accomplished with multinuclear NMR and UV-vis spectroscopy, FAB mass spectrometry, and X-ray crystallography. The length of these metallamacrocycles ranges from 2 to 3 nm. Postmodification via non-nucleophilic counterion exchange results in enhanced structural integrity for the assemblies.
