A Ring‐Opening Metathesis Polymerization Catalyst That Exhibits Redox‐Switchable Monomer Selectivities
Abstract
A ring‐opening metathesis polymerization catalyst supported by a redox‐active N‐heterocyclic carbene was synthesized and found to undergo reversible reduction. In its neutral form, the catalyst polymerized 1,5‐cis,cis‐cyclooctadiene at a higher rate than that of a norbornene derivative; however, upon reduction, the selectivity was found to reverse. Utilizing this oxidation state dependent selectivity, a series of copolymers with controlled compositions, microstructures, and physical properties were prepared by redox‐switching the catalyst over the course of a series of polymerization reactions.
