McCurdy, Ryan D.; Jacobse, Peter H.; Piskun, Ilya; Veber, Gregory C.; Rizzo, Daniel J.; Zuzak, Rafal; Mutlu, Zafer; Bokor, Jeffrey; Crommie, Michael F.; Fischer, Felix R. published an article in 2021. The article was titled 《Synergetic Bottom-Up Synthesis of Graphene Nanoribbons by Matrix-Assisted Direct Transfer》, and you may find the article in Journal of the American Chemical Society.Product Details of 523-27-3 The information in the text is summarized as follows:
The scope of graphene nanoribbon (GNR) structures accessible through bottom-up approaches is defined by the intrinsic limitations of either all-on-surface or all-solution-based synthesis. Here, we report a hybrid bottom-up synthesis of GNRs based on a Matrix-Assisted Direct (MAD) transfer technique that successfully leverages tech. advantages inherent to both solution-based and on-surface synthesis while sidestepping their drawbacks. Critical structural parameters tightly controlled in solution-based polymerization reactions can seamlessly be translated into the structure of the corresponding GNRs. The transformative potential of the synergetic bottom-up approaches facilitated by the MAD transfer techniques is highlighted by the synthesis of chevron-type GNRs (cGNRs) featuring narrow length distributions and a nitrogen core-doped armchair GNR (N4-7-ANGR) that remains inaccessible using either a solution-based or an on-surface bottom-up approach alone. The results came from multiple reactions, including the reaction of 9,10-Dibromoanthracene(cas: 523-27-3Product Details of 523-27-3)
9,10-Dibromoanthracene(cas: 523-27-3) is synthesized by the bromination of anthracene. The bromination reaction is carried out at room temperature using carbon tetrachloride as a solvent. Using 80-85% anthracene as raw material, adding bromine to react for half an hour, the yield is 83-88%.Product Details of 523-27-3
