Simultaneous replication of such phototropic movement and volumetric growth in synthetic polymers is important but currently remains challenging. Here, the molecular design of a photoswitchable tricyanofuran (TCF) based hydrogel is reported that can concurrently display such phototropic movement and self‐growth in water under stimulation of light and pH. The macroscale growth of the hydrogel originates directly from the volume swelling induced by charge rise of TCF upon isomerization, which dramatically facilicates water/nutrients diffusion into the network. As the growing rate under each stimulation is independently regulated, TCF hydrogels are successfully developed displaying heterogeneous growth accompanied with phototropic bending deformation by taking the advantage of the differential growing rates induced by light and pH. Importantly, the phototropic deformation direction after secondary polymerization growth can be reversibly switched between positive and negative states modulating light irradiation and pH conditions. This tunability enables biomimetic replication of natural light‐responsive systems. The work provides a novel molecular design strategy for advancing the development of biomimetic systems with capability of phototropic deformation and self‐growth.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"26 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, natural biomass‐derived materials have demonstrated tremendous potential due to their inherent renewability, superior biocompatibility, and unique structural skeletons. This study proposes a rational molecular design strategy to produce rosin‐derived dehydroabietic acid‐quinoxaline (DAQx) as a natural electron acceptor, and triphenylamine is incorporated as an electron donor to construct a donor–acceptor (D–A) type structure. This approach develops biomass‐based aggregation‐induced emission (BioAIE) materials with twisted intramolecular charge transfer characteristics. By adjusting the conjugation extent and electron‐withdrawing capability of the DAQx skeleton, dynamic optimization of photophysical properties is achieved. The results indicate that the modified D–A‐type BioAIE materials not only exhibit remarkable solvent stimuli‐responsive behavior, enabling dynamic encryption‐decryption, but also realize precisely targeted imaging of subcellular organelles, benefiting from the inherent biocompatibility of the natural DAQx skeleton.
