structure‐dependent electronic properties. Here, we describe the on‐surface synthesis of an unprecedented cove‐edge chiral GNR with a benzo‐fused backbone on a Au(111) surface using 2,6‐dibromo‐1,5‐diphenylnaphthalene as precursor. The initial precursor self‐assembly and the formation of the chiral GNRs upon annealing are revealed, along with a relatively small electronic bandgap of approximately 1.6 eV, by
手性石墨烯纳米带代表一类重要的石墨烯纳米材料,具有扶手椅和锯齿形边缘的不同组合,赋予它们独特的结构依赖性电子特性。在这里,我们描述了使用2,6-二溴-1,5-二苯基萘作为前体在Au(111)表面上具有苯并稠合骨架的前所未有的凹形边缘手性GNR的表面合成。通过扫描隧道显微镜和光谱学,揭示了初始的前体自组装和退火后手性GNR的形成,以及相对较小的约1.6 eV电子带隙。
