Redox‐Generated Mechanical Motion of a Supramolecular Polymeric Actuator Based on Host–Guest Interactions

Abstract

A supramolecular hydrogel is formed by a water-soluble polymer cross-linked with host–guest inclusion complexes between cyclodextrin and ferrocene. Dissociation and re-formation of inclusion complexes by redox stimuli lead to macroscale expansion and contraction of the hydrogel. The gel is utilized as a redox-responsive actuator and the mechanical work done is evaluated.
