Inside Cover: Photo‐RAFT Polymerization for Hydrogel Synthesis through Barriers and Development of Light‐Regulated Healable Hydrogels under NIR Irradiation (Angew. Chem. Int. Ed. 25/2023)

Hydrogel preparation under NIR light via a photoinduced RAFT polymerization catalyzed by tetrasulfonated zinc phthalocyanine is reported Cyrille Boyer et al. in their Research Article (e202302451). Exploiting enhanced penetration of light, gelation effectively performed through barriers. Thiocarbonylthio groups embedded hydrogel networks facilitate the reactivation polymer chains wavelengths, enabling healing hydrogels non-transparent
