Ring-opening polymerization is used to prepare polyesters with precisely controlled mol. weights, mol. weight distributions, and tacticities. Herein, we report a Co/Zn catalytic system that can be activated by an elec. current to mediate efficient ring-opening polymerization of enantiopure O-carboxyanhydrides, allowing for the synthesis of isotactic functionalized polyesters with high mol. weights (>140 kDa) and narrow mol. weight distributions (Mw/Mn < 1.1). We also demonstrate that these catalysts can be used for stereoselective ring-opening polymerization of racemic O-carboxyanhydrides to synthesize syndiotactic or stereoblock copolymers with different glass transition temperatures compared with their atactic counterparts.
