The article presents a novel method for fabricating reconfigurable hydrogel assemblies using a photocontrolled metallopolymer adhesive. This adhesive, composed of a Ru-containing polymer and a thioether-containing polymer, allows for reversible gluing of hydrogel units via metal–ligand coordination and polymer chain entanglement. The hydrogel assemblies, containing temperature- and pH-responsive units, exhibit controllable shape changes and motions in response to external stimuli. The assemblies can be disassembled by light irradiation and reassembled using heating, enabling the reconfiguration of their structures and functions. The study demonstrates the potential of this approach for designing intelligent materials and soft robots with user-defined functions, highlighting the unique combination of photocontrolled Ru–Coordination and polymer chain entanglement in creating strong yet reversible adhesives.The article presents a novel method for fabricating reconfigurable hydrogel assemblies using a photocontrolled metallopolymer adhesive.
