From the structure point of view, there are a number of ways of tiling a carbon sheet with different polygons, resulting in prospects of tailoring electronic structures of low-dimensional carbon nanomaterials. However, up to now, the experimental fabrication of such structures embedded with periodic nonhexagon carbon polygons, especially ones with more than three kinds, is still very challenging, leaving their potential properties unexplored. Here we report the bottom-up synthesis of a nanoribbon composed of 4–5–6–8-membered rings via lateral fusion of polyfluorene chains on Au(111). Scanning probe microscopy unequivocally determines both the geometric structure and the electronic properties of such a nanoribbon, revealing its semiconducting property with a bandgap of ∼1.4 eV on Au(111). We expect that this work could be helpful for designing and synthesizing complicated carbon nanoribbons.

由 4-5-6-8 元环组成的碳纳米带的表面合成
从结构的角度来看,有多种方法可以将碳片拼接成不同的多边形,从而为低维碳纳米材料的电子结构定制提供了前景。然而,到目前为止,这种嵌有周期性非六边形碳多边形的结构的实验制造,尤其是三种以上的结构,仍然非常具有挑战性,其潜在特性尚未得到探索。在这里,我们报告了通过 Au(111) 上聚芴链的横向融合由 4-5-6-8 元环组成的纳米带的自下而上合成。扫描探针显微镜明确地确定了这种纳米带的几何结构和电子特性,揭示了其在 Au(111) 上带隙为~1.4 eV 的半导体特性。
