Abstract
Mechanically active [c2]daisy chain rotaxanes were functionalized with mesogens to display liquid-crystalline properties. It was shown that the mechanical actuation of such bistable rotaxanes (between their contracted and extended states) modifies the transition temperature between their isotropic and smectic phases. In addition, small angle X-ray scattering (SAXS) experiments revealed a modification of the smectic phase corresponding to the modification of the interlayer distance as controlled by the mechanical bond. The work described by N. Giuseppone and co-workers in their Research Article opens new opportunities to implement [c2]daisy chain rotaxanes in responsive materials.
