石墨烯纳米带是下一代碳材料，吸引了各个研究领域的许多研究人员。它们的独特性质，如带隙、导电性、载流子迁移率、热导率、自旋极化和开关行为，在很大程度上取决于结构因素，如边缘结构、宽度和长度。因此，以原子精度控制这些结构因素的石墨烯纳米带的合成是至关重要的。在各种合成方法中，自下而上的合成方法如表面聚合和溶液相聚合代表了控制石墨烯纳米带的宽度、长度和边缘结构的有前途的方法。本文介绍了近年来报道的石墨烯纳米带的自下而上合成方法及其物理性质和应用的理论和实验研究。回顾这些研究沿着突出的优点和局限性，我们强调如何结构控制合成是重要的，并提供了未来的展望石墨烯纳米科学。
Graphene nanoribbons are the class of next-generation carbon materials that are attracting many researchers in various research fields. Their unique properties, such as band gap, conductivity, carrier mobility, thermal conductivity, spin polarization, and on-off behavior, heavily depend on structural factors such as edge structure, width, and length. Therefore, the synthesis of graphene nanoribbons with control over these structural factors with atomic precision is crucially important. Among various synthetic approaches, bottom-up synthetic methods such as on-surface polymerizations and solution-phase polymerizations represent promising ways to control the width, length, and edge structure of graphene nanoribbons. In this Perspective, we introduce the recently reported bottom-up synthetic methods for graphene nanoribbons and the theoretical and experimental research on those physical properties and applications. Reviewing these researches along with highlighting advantages and limitations, we emphasize how structurally controlled synthesis is important and provides future outlooks in graphene nanoribbon science.
