A thermoresponsive crown ether/amine-type rotaxane switch worked under solvent-free condition was developed. The wheel component moved to switch the local position on the axle by the solid-state acid base reaction between tert-amine moiety of the rotaxane and trichloroacetic acid. The wheel shuttling on the axle proceeded via neutralization by heating and protonation with trichloroacetic acid, being confirmed by H-1 NMR and TGA.
