Sustainable Functionalization of Pyrene: A Green Chemistry Approach for Advanced Materials
No full textSubstituted pyrene compounds are versatile building blocks for advanced materials with tunable properties, applicable in organic photovoltaics (OPVs), organic light-emitting diodes (OLEDs), precursors to metal-organic frameworks (MOFs) for luminescence sensing, photocatalysis, and electrochemical applications. Direct functionalization of pyrene can suffer from regioselectivity issue while indirect methods offer greater regiochemical control but add complexity. This motivates the development of alternative approaches, such as the DMSO-based strategy explored in our research where it acts a source of the methyl (methylene) sulfonium cation, an intermediate with a positively charged sulfur atom bonded to methyl and methylene groups and facilitates diverse transformations due to sulfur\u27s ability to stabilize adjacent negative charge. Our strategy involves activating DMSO to generate the cation, followed by electrophilic aromatic substitution with pyrene. Subsequent transformations enable the introduction of various functionalities, including aldehydes, sulfoxides, and carboxylic acids, expanding the utility of pyrene derivatives. This study explores a novel DMSO-based methodology for the controlled functionalization of pyrene. DMSO serves as a masked formyl group equivalent, enabling efficient production of mono-, di-, tri-, and tetra-substituted pyrene aldehydes, along with pyrene sulfoxides and sulfides, thus broadening their application in advanced material development.https://digital.library.ncat.edu/gradresearchsymposium25/1190/thumbnail.jp

The Relationship Between Market Characteristics and Players\u27 Salaries in the WNBA
No full textThis study examines the relationship between market characteristics, player nationality, and compensation in the Women’s National Basketball Association (WNBA), addressing gaps in understanding foreign player wage dynamics. Utilizing a unique dataset of WNBA contracts from 2017 to 2023, we analyze how city demographics influence salaries, particularly for foreign players without NCAA experience. Using weighted least squares (WLS) models, we find that foreign players earn higher wages the higher the share of the white population of the metropolitan area where the team resides. This effect is stronger for foreign players who did not attend U.S. colleges, emphasizing the role of consumer characteristics and preferences in shaping salary structures. Our study provides important implications for team composition and contract negotiation strategies that are particularly relevant to these firms facing restrictions on overall expenses on player compensation. Our future research aims to investigate if signing foreign players is linked to changes in attendance, gate revenue, and team performance.https://digital.library.ncat.edu/honorscollegesymposium25/1037/thumbnail.jp
