    Abstract: Metallopolymers composed of polymers and catalytically active diiron-disulfide ([2Fe-2S]) complexes are described herein. [FeFe]-hydrogenase mimics have been synthesized and used to initiate polymerization of various monomers to generate metallopolymers containing active [2Fe-2S] sites which serve as catalysts for a hydrogen evolution reaction (HER). Vinylic monomers with polar groups provided water solubility relevant for large scale hydrogen production, leveraging the supramolecular architecture to improve catalysis. Metallopolymeric electrocatalysts displayed high turnover frequency and low overpotential in aqueous media as well as aerobic stability. Metallopolymeric photocatalysts incorporated P3HT ligands to serve as a photosensitizer to promote photoinduced electron transfer to the active complex.

    Abstract: Sulfur composites and polymeric materials having a high sulfur content and prepared from elemental sulfur as the primary chemical feedstock. The sulfur copolymers are prepared by the polymerization of elemental sulfur with one or more monomers of amines, thiols, sulfides, alkynylly unsaturated monomers, nitrones, aldehydes, ketones, thiiranes, ethyienicaily unsaturated monomers, or epoxides. The sulfur copolymers may be further dispersed with metal or ceramic composites or copoiymerized with elemental carbon, photoactive organic chromophores, or reactive and solubilising/biocompatib!e moieties. The sulfur composites and polymeric materials feature the ability self-healing through thermal reformation. Applications utilizing the sulfur composites and polymeric materials may include electrochemical cells, optics, H 2 S donors and antimicrobial materials.

    Abstract: Copolymerization of elemental sulfur with functional comonomers afford sulfur copolymers having a high molecular weight and high sulfur content. Nucleophilic activators initiate sulfur polymerizations at relative lower temperatures and in solutions, which enable the use of a wider range of comonomers, such as vinylics, styrenics, and non-homopolymerizing comonomers. Nucleophilic activators promote ring-opening reactions to generate linear polysulfide intermediates that copolymerize with comonomers. Dynamic sulfur-sulfur bonds enable re-processing or melt processing of the sulfur polymer. Chalcogenide-based copolymers have a refractive index of about 1.7-2.6 at a wavelength in a range of about 5000 nm - 8 μιτι. The sulfur copolymer can be a thermoplastic or a thermoset for use in elastomers, resins, lubricants, coatings, antioxidants, cathode materials for electrochemical cells, dental adhesives/restorations, and polymeric articles such as polymeric films and free-standing substrates. Optical substrates are constructed from the chalcogenide copolymer and are substantially transparent in the visible and infrared spectrum.
