Abstract：

The　bioluminescence　mechanisms　of　deep-sea　organisms　provide　innovative　ideas　for　biomimetic　design.　To　meet　the　detection　needs　in　low-light　deep-sea　environments,　the　development　of　soft　robots　with　high-brightness　luminescence　is　crucial　for　long-term　in　situ　observation.　Directly　incorporating　high-performance　fluorescent　molecules　into　hydrogel　matrices　presents　challenges:　fluorescent　molecules　tend　to　dissociate　in　physically　crosslinked　systems,　and　complex　aqueous　environments　may　lead　to　instability　in　the　material　structure.　These　issues　limit　the　fluorescence　stability　and　service　life　of　underwater　devices.　Inspired　by　the　behaviors　of　marine　organisms,　this　study　proposes　a　biomimetic　soft　actuator　with　high　fluorescence　intensity.　The　actuator　adopts　a　bilayer　hydrogel　structure,　where　the　luminescent　layer　(PT4B-N),　covalently　crosslinked　with　fluorescent　molecules,　achieves　a　high　photoluminescence　quantum　yield　(PLQY　＞　60%),　and　the　pH-responsive　driving　layer　(PNPC)　enables　motion　control　(strip-shaped　hydrogel:　maximum　bending　angle　≈360°,　cycle　time　≈20 min).　The　experimental　results　demonstrate　that　the　actuator　can　realize　biological-like　synergic　fluorescence　and　shape　change　(SFSC)　behavior.　©　2025　Wiley-VCH　GmbH.
