Abstract

Abstract : Organocatalytic orthogonal atom transfer radical polymerization and ring-opening polymerization have been achieved using a single designer dual-function photocatalyst. Abstract : Orthogonal catalysis is emerging as a powerful method for the synthesis of block copolymers. By employing a single designed dual-function photoredox phosphoric acid catalyst (Photo-PA), two types of polymerizations via different mechanisms, photo-triggered organocatalyzed atom transfer radical polymerization and acid-triggered ring-opening polymerization, can be effectively bridged, discriminated and performed simultaneously in one pot. This orthogonal system also features metal-free conditions, visible light regulation, the use of a single catalyst, as well as good compatibility and control, allowing the synthesis of block copolymers with the desired component and low dispersity in a one-pot approach and controlled manner.
