通过共价键形成和氨解反应，成功地合成了一种新型的[3]轮烷，该轮烷由两个25元冠烷和一个带有两个芳基端基的轴分子组成，它可以将铯离子以1：1的夹心型络合物的形式引入到两个大环之间的空间中，而它与锂离子形成的是1：2的络合物。
A novel [3] rotaxane composed of two 25-membered crowno-phanes and one axle molecule having two anthryl end groups was successfully synthesized via covalent bond formation followed by aminolysis, and can incorporate caesium ion into the space between the two macrocycles as a 1 : 1 sandwich-type complex, whereas it makes a 1 : 2 complex with lithium ion.
