Front Cover: Dual‐Responsive Gradient Structured Actuator via Photopolymerization‐Induced Diffusion (Chem. Eur. J. 33/2024)

A gradient structured film has been fabricated through photopolymerization‐induced diffusion. First, illumination with low‐intensity UV light initiates the thiol‐ene reaction only at the surface, and this triggers the diffusion of thiol molecules to the surface. Then, illumination with blue light in...

Zusammenfassung:A gradient structured film has been fabricated through photopolymerization‐induced diffusion. First, illumination with low‐intensity UV light initiates the thiol‐ene reaction only at the surface, and this triggers the diffusion of thiol molecules to the surface. Then, illumination with blue light initiates chain‐growth acrylate homopolymerization, which arrests the spatial gradient of crosslink density. Due to its gradient structure, the film exhibits bending actuation both in air and solvent. More information can be found in the Research Article by D. Liu and co‐workers (DOI: 10.1002/chem.202400515).
