Synthesis of Functional Polymer Materials via Thiol-Ene/Yne Click Chemistry

Click chemistry has drawn considerable attention in less than a decade due to its unique advantages,such as simple reaction conditions,high reaction efficiency,high yield,easy post-treatment and high selectivity for the obtained products.Recently,as a new and efficient click reaction,thiol-ene/yne click chemistry has raised much interest and will probably be the main direction for development in click chemistry.On the other hand,synthesis of high-performance functional polymer materials is one of the hot topics of novel material research.In this review,we introduce the characteristics,advantages and reaction mechanism of thiol-ene/yne click chemistry.Research progresses of thiol-ene/yne click chemistry in functional polymer synthesis are highlighted,with focus on the synthetic route of linear,hyperbranched,cross-linked and other types of functional polymers via this method.The monomer features,product features and potential applications of different types of functional polymer materials synthesized by thiol-ene/yne click reaction are also discussed in detail.Furthermore,the problems in thiol-ene/yne click chemistry that still should be resolved are pointed out,and future applications are prospected.
