点击化学由于其高效、可靠、高选择性等特点,一经提出便在复杂结构聚合物制备上得到广泛关注,而活性自由基聚合则具有聚合过程和聚合物结构可控等特点。本文综述了点击化学与活性自由基聚合方法如原子转移自由基聚合(ATRP),可逆加成断裂链转移聚合(RAFT),氮氧调控活性自由基聚合(NMP),以及原子转移氮氧自由基聚合反应(ATNRC)等联用构建各种特殊结构聚合物,包括星型,梳型,刷型,蝌蚪型,8字型,H型,树枝状等特殊结构聚合物最新进展,并对点击化学与活性自由基聚合技术联用的发展趋势进行了展望。
Considerable attention has focused on the preparation of polymers with complicated structures via click chemistry due to high efficiency,reliable,high selectivity of click chemistry. On the other hand, living radical polymerization can control the polymerization and polymer structures effectively. This review highlights the development of the synthesis of well-defined polymers such as star-shaped, comb-shaped, brush-shaped, tadpole- shaped,figure-of-eight-shaped, H-shaped, and dendrimer-like polymers via a combination of click chemistry and living radical polymerization such as atom transfer radical polymerization (ATRP), reversible addition- fragmentation chain transfer polymerization (RAFT), nitroxide-mediated polymerization (NMP), and atom transfer nitroxide radical coupling ( ATNRC). Moreover, based on the recent progress, it has a prospect for the combination of click chemistry and living radical polymerization.
