摘 要:环状聚合物具有不同于线性高分子的独特性质,是一类具有应用前景的新型聚合物材料,但复杂的结构导致其合成过程复杂繁琐."点击"化学由于其高效、可靠、高选择性的特点已成为拓扑高分子合成的新方法,活性自由基聚合(ATRP、RAFT和NMP)具有聚合物结构可控等特点,二者联用为环状聚合物的合成拓宽了思路.本文就近几年"点击"反应、"点击"反应与活性自由基聚合联用以及其他方法联用在环状聚合物中的应用进行综述."点击"反应与这些方法的结合将在功能性环状聚合物的设计与合成中发挥积极的作用.Cyclic polymer is a kind of new polymeric material,which exhibits unique properties compared with linear polymers and has broad application prospect.However,the synthesis method is intricate because of its inherent complex structures.Click reactions,which coined by Sharpless,with the characteristic of high efficient,reliable and high selectivity and have been used as a new synthetic method of topological polymers.Living radical polymerization,such as atom transfer radical polymerization (ATRP),reversible addition-fragmentation chain transfer polymerization (RAFT) and nitroxide-mediated polymerization (NMP),can effectively control the polymerization and polymer structures.The combination of these two methods makes the synthesis of cyclic polymers easier.In this review,we briefly summarize the applications of click chemistry,click chemistry and living radical polymerization,click chemistry and other methods in the synthesis of cyclic polymers in the last few years.The combined click reaction and the above techniques are believed to play a positive role in the design and synthesis of functional cyclic polymers.
