Daisy chain architectures, a family of supramolecular and mechanically interlocked molecules, have significantly influenced the research on artificial molecular machines and have potential applications in various areas.
Daisy chain architectures, made by the self-complementary threading of an axle covalently linked to a macrocycle, represent a particularly intriguing family of supramolecular and mechanically interlocked (macro)molecules. In this review, we discuss their recent history, their modular chemical structures, and the various synthetic strategies to access them. We also detail how their internal sliding motions can be controlled and how their integration within polymers can amplify that motions up to the macroscopic scale. This overview of the literature demonstrates that the peculiar structure and dynamics of daisy chains have already strongly influenced the research on artificial molecular machines, with the potential to be implemented from nanometric switchable devices to mechanically active soft-matter materials. We review recent progresses in the synthesis and the use of daisy chain architectures as molecular machines and stimuli-responsive materials.
