Açıklama

Well-defined star polymers consisting of tri-, tetra-, or octa-arms have been prepared via coupling-onto strategy using photoinduced copper(I)-catalyzed 1,3-dipolar cycloaddition click reaction. An azide end-functionalized polystyrene and poly(methyl methacrylate), and an alkyne end-functionalized poly(epsilon-caprolactone) as the integrating arms of the star polymers are prepared by the combination of controlled polymerization and nucleophilic substitution reactions; whereas, multifunctional cores containing either azide or alkyne functionalities were synthesized in quantitatively via etherification and ring-opening reactions. By using photoinduced copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction, reactive linear polymers are simply attached onto multifunctional cores to form corresponding star polymers via coupling-onto methodology. The chromatographic, spectroscopic, and thermal analyses have clearly demonstrated that successful star formations can be obtained via photoinduced CuAAC click reaction.
