In this review, we provide a brief history, progress, and applications, discuss the remaining challenges of photocontrolled reversible addition-fragmentation chain transfer (RAFT) polymerization (i.e., photoinduced electron/energy transfer-RAFT (PET-RAFT), photoiniferter, photomediated cationic RAFT polymerization). Among these, visible-light-driven has attracted particular attention in recent years due to its benefits, including low energy consumption safe reaction procedure. Moreover, incorporation visible-light photocatalysis conferred attractive features, such as spatiotemporal control oxygen tolerance; however, clear understanding mechanism not been completely provided.

Photoinduced atom transfer radical polymerization (photo-ATRP) has risen to the forefront of modern polymer chemistry as a powerful tool giving access well-defined materials with complex architecture. However, most photo-ATRP systems can only generate radicals under biocidal UV light and are oxygen-sensitive, hindering their practical use in synthesis biohybrids. Herein, inspired by photoinduced electron transfer-reversible addition-fragmentation chain (PET-RAFT) polymerization, we demonstrate dual photoredox/copper catalysis that allows open-air ATRP green irradiation.

Photoinduced atom transfer radical polymerization (ATRP) has been proved to be a versatile technique for polymer network formation. However, the slow rates of typical ATRP limited its application in field additive manufacturing (3D printing). In this work, we introduced carbon quantum dots (CQDs) first time aqueous media and developed an ultrafast visible-light-induced system. After optimization, could achieve high monomer conversion (>90%) within 1 min, polydispersity index (PDI) was lower than 1.25. This system then applied as example 3D printing hydrogel through digital light processing (DLP), printed object exhibited good dimensional accuracy. Additionally, excellent stable optical properties CQDs also provided interesting photoluminescence capabilities objects.
