Fullerene-Attached Polymeric Homogeneous/Heterogeneous Photoactivators for Visible-Light-Induced CuAAC Click Reactions

Abstract

In this work, a visible-light -inducedcopper(I)-catalyzed azide alkyne cycloaddition (CuAAC) dick reaction via an electron transfer reaction employing fullerene (C-60) containing linear polystyrene and network polymer as homogeneous and heterogeneous activators, PS-C-60 and Gel-C-60, respectively, is described. Various low molar mass organic and polymeric azide and alkyne compounds are used to conduct the click reaction, and almost quantitative yields are attained. Compared to the bare C-60, the polymers with C-60, units exhibited a much higher promoting effect to catalyze CuAAC reactions.
