摘要

"Click" chemistry, proposed by Sharpless in 2001, has become a powerful and versatile synthetic tool because of some unique advantages, such as mild and simple reaction conditions, high efficiency and selectivity, and exceptional tolerance towards a wide range of functional groups and reaction conditions. In this review, the development of "click" chemistry (e. g., its history, characteristics and classifications) is firstly introduced. Subsequently, this paper focuses on the applications of "click" chemistry in the synthesis of a variety of topological polymers, including linear, brush-shaped, star-like, cyclic polymers, and dendrimers. Finally, the limitations and prospects of "click" chemistry are also discussed.
