冠醚的最重要的特性是能作为主体(host)分子与作为客体(guest)的周期表中的大多数金属离子、铵离子以及伯胺盐等阳离子络合。七十年代初Cram小组合成了一系列含联萘基的手征性(chirality)冠醚作为对映异构体的识别剂(recognitor)从而给仿生化学开拓了新途径。随后,Stoddart和Lehn等小组合成了其它类型的手征性冠醚并应用于模拟酶的研究。本文就手征性冠醚 The most important characteristic of crown ethers is that they can be used as host molecules to complex with the cations of most metal ions, ammonium ions and primary amine salts in the periodic table as a guest. In the early seventies, the Cram team synthesized a series of binaphthyl-containing chirality crown ethers as recognizers for enantiomers, opening up new avenues for biomimetic chemistry. Subsequently, Stoddart and Lehn et al. Synthesized other types of chiral ethers and applied them to the study of mimic enzymes. This article on the chiral crown ether
