Abstract

We describe a calix[6]arene‐based wheel that binds, in non‐polar media, a stilbazolium salt to yield a mixture of pseudorotaxane orientational isomers. The isomers abundance ratio evolves with time and can be reversibly tuned by playing on temperature. The spectroscopic properties, and notably the emission spectrum, of the bound guest depend on its orientation inside the non‐palindromic wheel, suggesting such a system as a switch with spectroscopic readout.
