Abstract

Biomimetic motion has advanced soft robotic materials. Common photoresponsive polymeric materials can sustain soft actuating robotic functions, while supramolecular soft robotics provide unprecedented structural and functional roles, e.g., stimuli-responsiveness, intrinsic supramolecular dynamicity, and bioactive cell-material interfaces. However, the high structural requirements of hierarchical supramolecular assembly are crucial for the fabrication of supramolecular soft robotics, limiting its technological development. We demonstrate a generation of supramolecular soft robotics without high orientation order and structural uniformity, capable of sustaining macroscopic actuation. A highly charged supramolecular nanoassembly of spiropyran amphiphiles entraps water at the macroscopic state and releases water upon photoisomerization, resulting in macroscopic soft actuating robotic functions.
