Abstract
Postpolymerization modification is a critical strategy for the development of functional polycarbonate scaffolds for medicinal applications. To expand the scope of available postpolymerization functionalization methods, polycarbonates containing pendant thioether groups were synthesized by organocatalyzed ring-opening polymerization. The thioether group allowed for the postpolymerization ring-opening of functional epoxides, affording a wide variety of sulfonium-functionalized A-B diblock and A-B-A triblock polycarbonate copolymers. The pendant thioether groups were found to be compatible with previously developed postsynthesis functionalization methods allowing for selective and orthogonal modifications of the polycarbonates.
