通过自下而上方法可获得的石墨烯纳米颗粒（GNR）结构的范围由全表面或全溶液基合成的固有限制限定。在这里，我们报告了一个混合自下而上的GNRs合成的基础上，矩阵辅助直接（MAD）的转移技术，成功地利用了固有的技术优势，解决方案为基础的和表面上的合成，同时避开他们的缺点。在基于溶液的聚合反应中严格控制的关键结构参数可以无缝地转化为相应GNR的结构。通过合成具有窄长度分布的人字形GNR（cGNR）和氮芯掺杂的扶手椅型GNR（N-4-7-ANGR），突出了MAD转移技术促进的协同自下而上方法的变革潜力，该扶手椅型GNR（N-4-7-ANGR）单独使用基于溶液或表面自下而上的方法仍然无法获得。
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 technical 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 (N-4-7-ANGR) that remains inaccessible using either a solution-based or an on-surface bottom-up approach alone.
