本文描述了一种将金属配体和冠醚-二烷基铵自组装技术结合到金属环三[2]拟轮烷的有效合成中的方法。由于所采用的两种非共价组装策略的正交性，这些多功能超分子可以通过九个独立组分的逐步或一锅组装来制备。这种方法展示了正交自组装的力量，并可能扩展到使用两个识别基序，希望模仿生物系统的复杂多功能。
A method of incorporating both metal-ligand and crown ether-dialkylammonium self-assembly techniques in the efficient synthesis of metallacyclic tris[2]pseudorotaxanes is described. These multifunctional supramolecules can be prepared by the stepwise or one-pot assembly of nine separate components on account of the orthogonality of the two noncovalent assembly strategies employed. This methodology demonstrates the power of orthogonal self-assembly and may be expanded beyond the use of two recognition motifs in hopes of mimicking the complex multifunctionality of biological systems.
