In this review, we provide a brief history, progress, and applications, and discuss the remaining challenges of photocontrolled reversible addition-fragmentation chain transfer (RAFT) polymerization (, photoinduced electron/energy transfer-RAFT (PET-RAFT), photoiniferter, and photomediated cationic RAFT polymerization). Among these, visible-light-driven RAFT polymerization has attracted particular attention in recent years due to its benefits, including low energy consumption and the safe reaction procedure. Moreover, the incorporation of visible-light photocatalysis in the polymerization has conferred attractive features, such as spatiotemporal control and oxygen tolerance; however, a clear understanding of the reaction mechanism has not been completely provided. We also present recent research efforts to elucidate the polymerization mechanisms with the aid of quantum chemical calculations combined with experimental evidence. This review offers an insight into the better design of polymerization systems for desired applications and helps realize the full potential of photocontrolled RAFT polymerization in both academic- and industrial-scale applications.
在这篇综述中，我们提供了光控可逆加成-断裂链转移（RAFT）聚合（光诱导电子/能量转移-RAFT（PET-RAFT）、光引发剂和光介导的阳离子 RAFT 聚合）的简要历史、进展和应用，并讨论了其仍存在的挑战。在这些方法中，由于其具有低能耗和安全的反应过程等优点，可见光驱动的 RAFT 聚合近年来受到了特别关注。此外，将可见光光催化作用引入聚合反应中赋予了聚合反应时空控制和耐氧性等吸引人的特性；然而，其反应机理仍未被完全阐明。我们还介绍了最近的研究工作，这些工作借助量子化学计算结合实验证据阐明了聚合反应机制。本综述深入了解了聚合体系的更好设计，有助于实现光控 RAFT 聚合在学术和工业规模应用中的全部潜力。
