Cross-Linked Polymer Based On Zero-Dimensional (۰D) Carbon Quantum Dots Nanocomposites Containing Palladium. Synthesis, Identification And Application As A Catalyst To Promote Organic Reactions In The Green Condition

As carbon-based products become more crucial in the chemical and pharmaceutical industries, researchers and laboratory groups are constantly studying methods to improve efficiency and reduce side chemical pollutions. In this research, we utilized cost-effective and non-toxic zero-dimensional carbon quantum dots as a small and precise substrate to initiate several living radical polymerizations in various spatial reaction position and dimensions. Then, Various acrylamide derivatives were grown on its surface as network polymer. Finally, this Polymeric network was used as for palladium ligand catalyst and applied in Suzuki-Miyaura and Sonogashira C-C Cross-Coupling reactions. In consideration of the presence of a tiny carbon core within the fully encapsulating carbon core-shell structure, the active functional groups facilitate enhanced accessibility for the catalyst to adsorb diverse agents, including individual metal ions. In current research, efforts were made to comply with the guidelines of sustainable chemistry and green chemistry. All reactions were conducted in aqueous media, minimized temperatures necessity and employing low toxic and highly recyclable anti solvents. Characterization of the synthesized materials was carried out using a suite of analytical techniques, including UV-Vis, FT-IR, NMR, SEM and ICP-MS methods were used.Our findings demonstrate the potential of carbon quantum dots to revolutionize the production of advanced materials, including plastics and pharmaceuticals, by enabling precise control and efficiency in polymerization processes. The scalability of this technology also makes it feasible for industrial-scale applications, paving the way for a more sustainable and environmentally-friendly future for the chemical and pharmaceutical industries. Overall, the integration of carbon quantum dots in living radical polymerizations represents a significant step forward in the quest for greener and more efficient manufacturing processes, offering a more sustainable and environmentally-conscious approach to meeting industry demands.
