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

通过在三重对称超晶格中引入sp碳而超越sp2碳范式的类石墨烯二维化合物最近出现了。在第一个资助期的继续工作中，我们在这里提出了一种源自表面化学的自下而上的技术，该技术促进了石墨烯中sp/sp2的生产，即所谓的石墨胺。由于其自下而上的合成方法，提出了具有金属有机前体分子的二维碳片的共价模块化功能化。特别是磁性前体的功能化可能导致具有分子自旋阀器件潜力的有趣材料；这是我们在第一个资助期引入的概念。在这里，我们提出(I)（功能）石墨烯的表面合成，（II）从原始（生产）衬底分离和转移石墨烯的过程，以促进其内在电学和光学性质的研究。（三）新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.
