实现Borromean链接在一个完全合成的分子形式的报告。这个链接，这是拓扑非手性的，从18个组件的模板定向形成的12个亚胺和30配价键，与三个互锁的大环，每个tetranucleating和decadentate整体的协调，共六个锌（II）离子的自组装，是近定量。三个大环存在对角成对，六个外二齿联吡啶和六个内二亚氨基吡啶配体的六个锌（II）离子。协同使用配位、超分子和动态共价化学允许通过多个协同自组装过程高效构建直径约为2.5纳米的纳米级十二碳环，内腔体积为250埃（3），内衬12个氧原子。
The realization of the Borromean link in a wholly synthetic molecular form is reported. The self-assembly of this link, which is topologically achiral, from 18 components by the template-directed formation of 12 imine and 30 dative bonds, associated with the coordination of three interlocked macrocycles, each tetranucleating and decadentate overall, to a total of six zinc(II) ions, is near quantitative. Three macrocycles present diagonally in pairs, six exo-bidentate bipyridyl and six endo-diiminopyridyl ligands to the six zinc(II) ions. The use, in concert, of coordination, supramolecular, and dynamic covalent chemistry allowed the highly efficient construction, by multiple cooperative self-assembly processes, of a nanoscale dodecacation with an approximate diameter of 2.5 nanometers and an inner chamber of volume 250 Angstrom(3), lined with 12 oxygen atoms.
