A [2]rotaxane‐based molecular shuttle with an acid‐responsive asymmetric macrocycle on a symmetric dumbbell axle is reported. Upon adding TFA, the macrocycle, namely the amine naphthotube, is protonated and translocates from the di(quaternary ammonium) station to the triazole stations because of ele...
