Over the past decade, the bottom-up synthesis of structurally defined graphene nanoribbons (GNRs) with various topologies has attracted significant attention due to the extraordinary optical, electronic, and magnetic properties of GNRs, rendering them suitable for a wide range of potential applications (e.g., nanoelectronics, spintronics, photodetectors, and hydrothermal conversion). Remarkable achievements have been made in GNR synthesis with tunable widths, edge structures, and tailor-made functional substitutions. In particular, GNRs with liquid-phase dispersibility have been achieved through the decoration of various functional substituents at the edges, providing opportunities for revealing unknown GNR physiochemical properties. Because of the promise of liquid-phase dispersible GNRs, this mini-review highlights recent advances in their synthetic strategies, physiochemical properties, and potential applications. In particular, deep insights into the advantages and challenges of their syntheses and chemical methodologies are provided to encourage future endeavors and developments.

在过去的十年中，由于GNR的非凡的光学，电子和磁性特性，具有各种拓扑结构的结构确定的石墨烯纳米带（GNR）的自下而上的合成引起了广泛的关注，使其适用于广泛的潜在应用（例如，纳米电子，自旋电子，光电探测器和水热转换。GNR合成在宽度，边缘结构和量身定制的功能可调方面取得了令人瞩目的成就。特别是，通过在边缘装饰各种功能性取代基来实现具有液相分散性的GNR，从而为揭示未知的GNR物理化学性质提供了机会。由于有液相分散的GNR的前景，这份小型综述着重介绍了其合成策略，理化性质和潜在应用方面的最新进展。特别是，对它们的合成和化学方法的优点和挑战提供了深刻的见解，以鼓励未来的努力和发展。
