The properties of graphene nanoribbons are highly dependent on structural variables such as width, length, edge structure, and heteroatom doping. Therefore, atomic precision over all these variables is necessary for establishing their fundamental properties and exploring their potential applications. An iterative approach is presented that assembles a small and carefully designed molecular building block into monodisperse N-doped graphene nanoribbons with different lengths. To showcase this approach, the synthesis and characterisation of a series of nanoribbons constituted of 10, 20 and 30 conjugated linearly-fused rings (2.9, 5.3, and 7.7 nm in length, respectively) is presented.
石墨烯纳米带的性质高度依赖于结构变量，如宽度、长度、边缘结构和杂原子掺杂。因此，为了确定其基本性质并探索其潜在应用，需要对所有这些变量进行原子级精度的控制。本文提出了一种迭代方法，该方法将一个小而精心设计的分子构建块组装成具有不同长度的单分散 N 掺杂石墨烯纳米带。为了展示这种方法，本文合成并表征了一系列纳米带，它们由 10、20 和 30 个线性融合的共轭环组成（长度分别为 2.9、5.3 和 7.7nm）。
