Bottom-up synthesis of edge-engineered graphene nanoribbons

石墨烯纳米带(GNRs)是一种具有纳米级宽度的带状石墨烯缺口，由于其独特的光电和热电性质而引起了人们的广泛关注，被认为是一种很有前途的下一代电子学材料。它们的性质，如化学稳定性、光吸收和发射、载流子迁移率和自旋态，在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。这个项目的目的是用精确的边缘工程方法开发功能化GNR的解决方案状态自下而上的合成。将进一步探索具有不同化学部分的GNRs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，并将制造器件以了解边缘相关的电子性质。该项目与EPSRC/UKRI研究领域的“先进材料”主题相关。

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.
