Abstract
A bistable CB6-based [3]rotaxane with two recognition sites has been prepared very efficiently in a high yield synthesis through CB6 catalyzed 1,3-dipolar cycloaddition; this rotaxane behaves as a reversible molecular switch and exhibits conformational changes caused by the movement of rings under base, acid and heat stimuli from one location to the other.
摘要
一种具有两个识别位点的基于杯[6]芳烃的双稳态[3]轮烷，已通过杯[6]芳烃催化的1,3-偶极环加成反应，以高产率合成的方式非常高效地制备出来；这种轮烷表现为一种可逆分子开关，并在碱、酸和热刺激下，展示出因环从一个位置移动到另一个位置而引起的构象变化。
