Rotaxanes have garnered interest for their unique structures consisting of mechanically interlocked axles and macrocycles. Numerous organic macrocycles have been employed to construct rotaxanes, including crown ether, cyclobis(paraquat-p-phenylene), calixarene, pillararene, cyclodextrin, and cucurbituril.
