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.
