Synthesis of an ABC triblock copolymer by a bilateral Click reaction using α,ω-bifunctionalized poly(3-hexylthiophene) as an inner segment

Abstract

A novel ABC-type triblock copolymer, where A, B, and C were poly(methyl methacrylate) (PMMA), P3HT, and polystyrene (PS), respectively, was successfully synthesized by the bilateral Cu-catalyzed azide alkyne cycloaddition (CuAAC) reaction of α,ω-bifunctionalized P3HT with α-chain-end-functionalized PMMA and ω-chain-end-functionalized PS at a high yield.
