Graphene nanoribbons (GNRs), a ribbon-shaped cut-outs of graphene with nanometre-scale widths, have attracted much attention due to their unique optoelectronic and thermoelectric properties, and have been recognized as a promising material for next-generation electronics. Their properties, such as chemical stability, optical absorption and emission, charge-carrier mobility, and spin state, heavily depend on their geometrical features such as edge structure, width, and length. This studentship aims to develop solution-state bottom-up synthesis of functionalized GNRs with precise edge-engineering approaches. Further functionalization of GNRs with various chemical moieties will be explored. Self-assembly and supramolecular properties of these graphene nanostructures will be studied in detail and devices will be fabricated to understand the edge dependent electronic properties. This project is relevant to 'Advanced Materials' theme of EPSRC/UKRI research areas.

石墨烯纳米带（GNRs）是一种具有纳米级宽度的带状石墨烯，由于其独特的光电和热电性能而受到广泛关注，被认为是下一代电子材料的一种很有前途的材料。它们的性质，如化学稳定性、光学吸收和发射、载流子迁移率和自旋状态，很大程度上取决于它们的几何特征，如边缘结构、宽度和长度。本研究旨在以精确的边缘工程方法，发展解态自底向上的功能化gnr合成。我们将进一步探索各种化学基团对gnr的功能化。这些石墨烯纳米结构的自组装和超分子性质将被详细研究，器件将被制造来了解边缘依赖的电子性质。本项目与EPSRC/UKRI研究领域的“先进材料”主题相关。
