Using Acetate Anions To Induce Translational Isomerization in a Neutral Urea‐Based Molecular Switch

Abstract

Vying for urea: The translational isomerism of a neutral [2]rotaxane can be controlled in solution through the addition and removal of acetate anions. In the absence of acetate ions, the macrocyclic host recognizes a diphenylurea derivative; recognition of acetate ions by the urea-based station causes relocation of the macrocycle to another binding site (see picture).
