Abstract: The present invention provides chalcogenide hybrid organic/inorganic polymers (“CHIPs” or organic chalcogenide polymers) and methods for producing and using the same. In particular, the chalcogenide hybrid organic/inorganic polymers of the invention comprise a hydrocarbon cyclic ring structure and one or more chalcogenide selected from the group consisting of sulfur, selenium, cyclic selenium sulfide, and a combination thereof.

Abstract: Catalyst systems employing inexpensive and readily-available protic co-catalysts to increase a proton reduction rate in a hydrogen evolution reaction (HER) are described herein. The protic co-catalysts function to increase the rate without being consumed in the process of water splitting to hydrogen and oxygen. They may simultaneously serve to stabilize the pH of the water and be the electrolyte to carry the current for the electrolytic splitting of water. The protic co-catalysts also decrease the overpotential energy requirement for the process of water splitting. These protic co-catalysts can be used with both heterogeneous and homogenous catalysts, as well as assist photocatalysis and other processes for the reduction of protons.

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: Methods of vulcanization using a high content sulfur polymer, instead of elemental sulfur, have been developed. These high sulfur content polymers are referred to as Chalcogenide Hybrid Inorganic/Organic Polymers (CHIP) materials and have good polymer compatibility in that they are soluble in a number of polymers. Furthermore, CHIP materials may have weaker bonds than the S—S bonds of elemental sulfur and thus provide for a higher crosslinking efficiency vulcanization.

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-8μιτι. 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.
