Sulfur and Selenium Bond Formation, Polymers, and Optical Materials
This community focuses on the chemical synthesis of sulfur- and selenium-containing molecules, with a strong emphasis on creating high-refractive-index polymers for optical applications and developing new methods for forming carbon-sulfur and carbon-selenium bonds.
The work centers on the synthesis of organosulfur and organoselenium compounds, frequently using catalytic cross-coupling, cyclization, and inverse vulcanization techniques. A significant portion of the research is dedicated to developing polymers with high refractive indices and transparency, suitable for optical components and thermal imaging. Additionally, the community explores the biological activity of these derivatives, including their potential as antioxidants and antimicrobial agents. Methods often involve mild conditions, metal-free catalysts, or copper-catalyzed reactions to access aryl halides and heterocycles. The recurring themes of "elemental sulfur," "inverse vulcanization," and "refractive index" highlight a dual focus on fundamental bond construction and the engineering of functional polymeric materials.
The community is most prominent in research tracked for Selenium, representing 4.1% of all selenium research, and Tellurium, representing 4.2% of all tellurium research. It also constitutes 1.6% of sulfur research, with 4,329 papers in this group.
The community comprises 20,958 papers, published primarily in Phosphorus, Sulfur, and Silicon and the Related Elements, Synthesis, and The Journal of Organic Chemistry.
Recent work continues to explore high-refractive-index cycloolefin-containing polymeric materials and bromide-catalyzed C–H selenylation of naphthalenes and pyridones. Other recent studies focus on covalent adaptable networks derived from itaconic acid and sulfur for adhesives, and the use of sulfur polymer optics for thermal imaging.
