Description
Summary:Three‐dimensional unidirectionally aligned and responsive supramolecular hierarchical assemblies have much potential in adaptive materials for biomedical and soft actuator applications. However, to achieve systematical control of the motion of stimuli‐responsive materials by orthogonal external stimuli and to complete a series of complicated tasks remains a grand challenge. Herein, we demonstrate a novel designed hybrid supramolecular assembly of molecular motor amphiphiles that also serves as a template for iron nanoparticles growth, and as a consequence this soft hybrid material is orthogonally controlled by dual light/magnetic stimuli. Macroscopic motor amphiphile strings, decorated with iron nanoparticles, provide fast response photoactuations and magnet induced movements that allows a precisely controlled cargo transport process. Unidirectionally aligned responsive supramolecular hierarchical assemblies have much potential in biomedical materials and soft actuators. Macroscopic motor amphiphile strings, decorated with iron nanoparticles, provide fast response photoactuation and magnet induced movements that allow a systematic cargo transport process.
