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.

石墨烯纳米纤维（GNRS）是具有纳米尺寸宽度的石墨烯的带状切口，由于其独特的光电和热电学特性，引起了很大的关注，并被公认为是下一代电子产品的有前途的材料。它们的特性，例如化学稳定性，光吸收和发射，电荷载体迁移率和自旋状态，在很大程度上取决于它们的几何特征，例如边缘结构，宽度和长度。该学生旨在通过精确的边缘工程方法开发解决方案状态的自下而上的综合。将探索具有各种化学部分的GNR的进一步功能。这些石墨烯纳米结构的自组装和超分子特性将进行详细研究，并将制造设备以了解边缘依赖性电子性能。该项目与EPSRC/UKRI研究领域的“先进材料”主题有关。
