Abstract Phototropism is ubiquitous in plants that endows them directional movement and substantial growth toward light sources. Simultaneous replication of such phototropic volumetric synthetic polymers important but currently remains challenging. Here, we report the molecular design a photoswitchable tricyanofuran (TCF) based hydrogel can concurrently display self-growth water under stimulation pH. The macroscale hdyrogel originates directly from charge rise TCF switch upon isomerization induced by or pH, which dramatically improves polymer hydrophilicity facilicates diffusion into network. As growing rate each independently regulated, successfully developed hydrogels displaying heterogeneous accompanied with bending deformation taking advantage differential rates Importantly, direction during process be flexibly switched to either positive negative tuning irradiation pH conditions for applications replicating structure function natural light-responsive systems. Our work provides novel strategy advancing development biomimetic systems capability self-growth.
