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

Abstract

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