Redox-active catalysts are described whose chemoselectivity for ring-opening polymerization reactions can be altered with the choice of metal precursor and oxidation state of the catalyst. Control over polymer composition, sequence, and architecture can be achieved through judicious choice of monomers and with in situ application of redox equivalents. Replacing chemical redox reagents with electrochemical potential provides access to redox-switching that is more ammenable to automation and that is also suitable for surface initiated polymerization reactions. Aspects of catalyst design, polymerization mechanism, and materials applications of the resulting polymers will be discussed.
