An efficient synthetic method toward graphene‐like molecules (GLMs), having four zigzag edges, is described. They were obtained as stable materials and their structures were confirmed by X‐ray crystallographic analysis. They exhibit topology‐ and size‐dependent electronic properties and global aromaticity, which are all different from GLMs having either all‐armchair edges, or three zigzag edges, or two armchair/two zigzag edges. They can be reversibly oxidized and reduced into stable charged species, which show fragmental aromatic character to minimize anti‐aromaticity. Our studies give some new insights into the electronic structures and properties of a new type of rarely studied GLMs.

具有四个锯齿形边缘的类石墨烯分子
描述了一种有效的合成方法,该方法可合成具有四个之字形边缘的石墨烯样分子(GLM)。它们以稳定的材料形式获得,其结构通过X射线晶体学分析得到了证实。它们显示出与拓扑和尺寸有关的电子特性和整体芳香性,这与具有全扶手椅边缘,三个锯齿形边缘或两个扶手椅/两个锯齿形边缘的GLM有所不同。它们可以被可逆地氧化并还原成稳定的带电物种,这些物种表现出碎片化的芳香特性,从而最大程度地降低了抗芳香性。我们的研究为新型的很少研究的GLM的电子结构和性质提供了一些新见解。
