This project aims at the surface-confined construction of advanced covalent nanomaterials from alkyne-based precursors and the characterization of their structural, chemical, and electronic properties at the single-molecule level. The desired comprehensive insight in the properties of the well-defined samples prepared under ultra-high vacuum conditions will be obtained by combining experimental methods providing complementary information. More specifically, low-temperature (5 K) scanning probe microscopy yielding real space images with submolecular features will be amended by synchrotron-based X-ray spectroscopic techniques with high energy resolution. By systemically investigating the involved aspects of the sample preparation process, we plan to achieve a profound understanding of the influence of the precursor design, the surface templating effect, and the reaction excitation type on the quality of the resulting nanomaterials. Furthermore, alternative coupling schemes and fabrication approaches will be investigated, such as atom tunneling- and catalytic adatom-mediated reactions or alkyne-halogen protocols combined with photon or electron excitation. The accumulated knowledge will provide the foundation for the atom-precise fabrication of novel carbon-based nanomaterials with impressive, tunable characteristics and functionalities highly desirable for future nanotechnology applications like high mechanical strength and flexibility, extreme charge carrier mobilities, and chemical versatility.

该项目旨在从炔基前体表面限制构建先进的共价纳米材料，并在单分子水平上表征其结构，化学和电子特性。通过结合提供补充信息的实验方法，将获得在超高真空条件下制备的定义明确的样品的性质所需的全面洞察。更具体地说，低温（5 K）扫描探针显微镜产生的真实的空间图像与亚分子功能将被修正同步加速器为基础的X射线光谱技术与高能量分辨率。通过系统地研究样品制备过程中所涉及的各个方面，我们计划对前驱体设计、表面模板效应和反应激发类型对所得纳米材料质量的影响有深刻的理解。此外，替代耦合方案和制造方法将被调查，如原子隧穿和催化adatom介导的反应或炔卤素协议结合光子或电子激发。积累的知识将为新型碳基纳米材料的原子精确制造提供基础，这些材料具有令人印象深刻的可调特性和功能，对于未来的纳米技术应用非常理想，如高机械强度和灵活性，极端的电荷载流子迁移率和化学多功能性。
