Based on liquid crystal elastomer (LCE) materials,

hierarchically structured soft actuators can meet some requirements for “human-friendly” working mode and execute

complex tasks with intelligent adaptation to environmental

changes. However, few researchers have paid much attention to

the preparation methods of multicomponent/hierarchical LCE

actuators. In this communication, we demonstrate the successful integration of an exchangeable diselenide chain extender for

the preparation of dynamic LCEs, which could be reprogrammed on heating or under visible light illumination. Moreover, the rearrangeable polydiselenide networks could be

applied to develop the self-welding technology toward fabricating hierarchically structured LCE actuators with sophisticated deformability without using any auxiliary reagent

(adhesive, tape, catalysts or initiator) during the assembling

process
