Cover Feature: Spacer Length‐Independent Shuttling of the Pillar[5]arene Ring in Neutral [2]Rotaxanes (Chem. Eur. J. 24/2018)

Abstract

[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. More information can be found in the Communication by T. Ogoshi and A. M. Brouwer et al. on page 6325.
