A novel [2](2)rotaxane 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 [2](2)rotaxane can be easily achieved by acid/base stimulus.
