| Abstract Scope |
Diazonium-based functionalization of graphene offers a promising pathway to enhance its functionality for applications in electronics, sensing, and quantum devices. This study investigates the impact of diazonium concentration and substrate choice on functionalization control. Preliminary data reveal that lower concentrations of 4-nitrobenzene diazonium (4-NBD) allow precise tuning of the defect-to-graphene ratio, maintaining graphene’s structural integrity, while higher concentrations induce significant defectivity. Substrate comparisons highlight the superior signal clarity and functionalization control achieved on silicon dioxide over copper. These findings establish a foundation for scalable methods to engineer graphene’s properties for specific functionalities, such as bandgap tuning for transistors or enhanced molecular sensing. Ongoing experiments aim to further delineate the relationship between reaction parameters and functional group integration, advancing the role of diazonium chemistry in developing next-generation functional materials. |
