Abstract
A novel 2rotaxane based on pentiptycene-derived bis(crown ether) can be efficiently synthesized via a "click chemistry" method and the subsequent N-methylation. Due to the different affinities of DB24C8 with the ammonium and triazolium stations, the wing-flapping movement of the DB24C8 "wings" in the 2rotaxane can be easily achieved by acid/base stimulus.
摘要
一种基于五并苯衍生的双冠醚的新型[2]轮烷可以通过“点击化学”方法和随后的 N-甲基化反应有效地合成。由于 DB24C8 与铵基和三唑基之间的亲和力不同，通过酸碱刺激很容易实现 DB24C8“翅膀”在[2]轮烷中的扇动运动。
