| Abstract: | The great achievements of click chemistry have encouraged polymer scientists to use this reaction in their field. This review assembles an update of the advances of using azide-alkyne click polymerization to prepare functional polytriazoles (PTAs) with linear and hyperbranched structures. The Cu(I)-mediated click polymerization furnishes 1,4-regioregular PTAs, whereas, the metal-free click polymerization of propiolates and azides produces PTAs with 1,4-regioisomer contents up to 90%. The PTAs display advanced functions, such as aggregation-induced emission, thermal stability, biocompatibility and optical nonlinearity. |
