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.

最近出现了通过将sp-碳引入三重对称超晶格而超越sp2碳范例的石墨烯类2D化合物。为了继续第一个资助期的工作，我们在这里提出了一种从表面化学衍生的自下而上的技术，该技术有助于在石墨烯中生产sp/sp2，即所谓的graphdyines。由于其自下而上的合成方法，提出了用金属有机前体分子共价模块化2D碳片。特别是磁性前体的功能化可能会导致在分子自旋阀设备中具有潜力的有趣材料;我们在第一个资助期间引入了这一概念。在这里，我们提出了（I）（功能）graphdyines的表面合成，（II）从原始（生产）基板的graphdiynes的分离和转移，以促进其内在的电气和光-光学性能的调查过程。(III)新材料在自旋电子器件中的应用。
