The polymers and copolymers described can incorporate monomeric species previously held to have too high an oxidation potential for successful use in oMLD, can exhibit unexpected redox chemistry from the adjustable incorporation of primary amine monomers and resulting azo functional groups, and show superior performance metrics when compared to polymers and copolymers synthesized by other methods.
