Abstract

A tough self-healing supramolecular photoresponsive actuator based on a 2-urea-4[1H]-pyrimidinone (UPy)-terminated host-guest slide-ring structure was designed. The supramolecular gel was revealed to be stretchable and tough. It achieved a tensile strength of 2.25 MPa with elongation at break of 533% and could lift beyond 900 times its own weight. Based on the special structure, its photoresponsive motion was as fast as 55° within 40 s under 365 nm irradiation. The gel also showed highly efficient self-healable ability and quick responsivity to temperature and humidity.
