On-Surface Synthesis of Graphene-like Superlattices_sp/sp2-Graphdiynes

石墨烯类2D化合物通过在三重对称超晶格中引入sp2碳，超越了sp2碳的范式，最近出现了。作为第一个资助期工作的继续，我们在这里提出了一种源自表面化学的自下而上的技术，该技术有助于在石墨烯中生产sp2/sp2，即所谓的石墨烯。由于其自下而上的合成方法，提出了用金属有机前驱体分子对2D碳片进行共价模块功能化的方法。特别是，磁性前体的功能化可能导致在分子自旋阀装置中具有潜力的有趣材料；这是我们在第一个资助期引入的概念。在这里，我们建议(I)表面合成(功能)石墨烯，(Ii)从原始(生产)底物上分离和转移石墨二炔的过程，以便于研究其内在的电学和光电性质。(3)新型材料在自旋电子器件中的应用。

Graphene like 2D compounds going beyond the sp2 carbon paradigm by the introduction of sp-carbons into three-fold symmetry superlattices have recently emerged. In continuation of the work for the first funding period, we propose here a bottom up technology deriving from surface chemistry which facilitates the production of sp/sp2 in graphene, so called graphdyines. Due to its bottom-up synthetic approach, covalent modular functionalization of the 2D carbon sheets with metallorganic precursor molecules is proposed. In particular functionalisation with magnetic precursors may lead to interesting materials with potential in Molecular Spin Valve devices; a concept we have introduced during the first funding period. Here, we propose (I) surface-synthesis of (functional) graphdyines, (II) a process for the detachment and transfer of the graphdiynes from the original (production) substrates to facilitate the investigation of their intrinsic electrical and photo-optical properties. (III) the use of the novel materials in spintronic devices.
