[2]Rotaxanes with two identical binding sites exhibit shuttling of the ring component between the two stations. For a series of neutral [2]rotaxanes consisting of a pillar[5]arene ring and axles possessing two stations separated by flexible spacers of different lengths, the ring shuttling between the stations was found to be independent of the spacer length.
