Non covalent [2]catenanes were synthesized in high yield as kinetic products or as thermodynamic products after completion of an equilibrium. These sophisticated architectures were assembled in two steps, from an oblique bis-zinc(II) porphyrin and two different dipyridyl chelates, by using Cu(I)-N interactions to assemble acyclic complexes and Zn(II)-N interactions to generate rings. (1)H NMR including 2D COSY and ROESY experiments were used to characterize each compound. Spectrophotometric titrations highlight the influence of geometry in terms of distances and angles in non covalent coordinated assemblies. In fact, it was proved that a perfect fit leads to highly stable coordination chemistry-assembled species.
非共价[2]轮烷是作为动力学产物或在平衡完成后作为热力学产物以高产率合成的。这些复杂的结构是通过使用 Cu(I)-N 相互作用组装非环配合物和 Zn(II)-N 相互作用生成环，从斜式双锌(II)卟啉和两个不同的二吡啶螯合物分两步组装而成的。（1）H NMR 包括 2D COSY 和 ROESY 实验用于表征每个化合物。分光光度滴定法突出了在非共价配位组装中距离和角度的几何形状的影响。事实上，事实证明，完美的契合导致高度稳定的配位化学组装体。
