An air-stable supported Cu(І) catalyst for azide-alkyne click polymerization
Authors/Creators
Description
An air-stable supported Cu(I) catalyst, CuI@PS-Phen, was designed and synthesized. CuI@PS-Phen can efficiently catalyze the click polymerization of diynes a and diazides b to produce soluble and thermally stable polytriazoles with high molecular weights (Mw up to 30800), and low copper residue content (down to 190 ppm) in high yields (up to 94.2%) under mild reaction conditions without the exclusion of oxygen.
