Abstract:
PET-RAFT(光致电荷/能量转移-可逆加成裂解链转移)技术,是结合传统RAFT聚合和光氧化-还原催化反应,借鉴光合作用而发展出一种可见光/红外光调控的活性自由基聚合技术。在传统RAFT热聚合中,用ppm量的光催化剂取代热引发剂,其中的链转移剂(RAFT试剂)兼具引发剂、链转移剂和链终止剂功能。
和其他活性自由基聚合相比,PET-RAFT除了具有能耗低、反应条件温和、设备简单、时间和空间可控、聚合速度可控等通用和实用的特性之外,还具备独特的高抗氧性、催化剂多样性和高化学选择性。在活性自由基聚合中,高抗氧性让聚合体系无需去氧,能用于流动反应器以轻松实现工业放大;光催化剂的选择包括过渡金属复合物、有机染料、叶绿素和细菌叶绿素、卟啉类化合物等,可以实现各种波段的可见光和红外光调控的活性聚合;高化学选择性能够简化特殊规整结构聚合物的制备,同时可以实现一些特殊的化学反应(选择性的光活化),能够精准制备序列可控的高分子。因此,PET-RAFT技术的发展不仅能够推动活性自由基聚合的工业化应用前景,能有力推动高分子材料的“绿色”合成方向的发展,还能够提供一些崭新的有机和高分子合成新思路。
Bios for Dr. Jiangtao Xu:
Dr. Xu is an ARC Future Fellow and Lecturer (Tenure) in School of Chemical Engineering, UNSW Sydney. He received his bachelor and PhD degree in polymer chemistry from Fudan University in 2007, where he focused on developing RAFT polymerization. Following the postdoctoral research in UNSW Australia and the University of Melbourne and industrial experience, he joined UNSW again to develop visible light-induced living polymerization and precision polymer synthesis. He was awarded Australian Research Coucil (ARC) Future Fellowship in 2016. He has more than 60 peer-reviewed journal articles in high-impact journals (e.g. JACS, Angew. Chem., Chem Rev., Chem. Soc. Rev., Chem. Sci. etc.), attracting More than 2000 citation and H-index of 26.
His current research interests include: Green chemistry and sustainable polymer synthesis; Precision polymer synthesis mimicking natural perfection; Photoredox catalysis for living polymerization; Advanced polymer materials for nanomedicine and bioengineering applications.
