low-temperature scanning tunneling microscope/ atomic force microscope

表面合成是化学、物理和材料科学相结合的新兴研究领域。特别是，表面合成已经发展成为一种有前途的自下而上的合成方法，用于制造定义良好和原子精确的纳米结构。与经典的有机溶液合成相比，表面合成允许通过低温扫描隧道和原子力显微镜研究和表征新型纳米结构。这种低温扫描隧道和原子力显微镜将推动前所未有的纳米结构的表面合成和表征。虽然两位提案人在表面合成方面都有出色的经验，但两个工作组的科学领域是互补的。由于一个强大的和已经建立的合作，这两个小组涵盖了整个光谱的表面合成，包括前体分子的有机合成。除了两个主要的提议者之外，其他四个研究小组已经对使用该仪器感兴趣，并强烈支持这一提议。所有六个研究小组都紧密相连，并由于拟议的合作研究中心“合成二维材料的化学”而进行合作。但是，我们非常欢迎其他感兴趣的研究小组使用该仪器。该仪器的研究重点是新型二维聚合物（包括二维有机共价聚合物和金属有机聚合物）、石墨烯纳米带、多环芳烃以及分子开关、机器和电子逻辑门的表面合成。除了通过低温扫描隧道显微镜和原子力显微镜进行合成和相应的可视化外，还将通过扫描隧道光谱研究电子性质，如带隙或轨道边界的能级。该装置的进一步重点将是开发新的反应方法，以在表面形成长石墨烯纳米带和高度结晶的二维聚合物。

The on-surface synthesis is a novel research area, which synergizes chemistry, physic and material science. In particular, the on-surface synthesis has been developing as a promising bottom-up synthesis for the fabrication of well-defined and atomically precise nanostructures. In contrast to the classical organic solution syntheses, the on-surface synthesis allows the investigation and characterization of novel nanostructures via low-temperature scanning tunneling– and atomic force microscopy. This proposed low-temperature scanning tunneling– and atomic force microscope will push the on-surface synthesis and characterization of unprecedented nanostructures. Although both proposers have excellent experiences in on-surface synthesis, the scientific fields of both working groups are complementary. Due to a strong and already established cooperation, both groups cover the whole spectrum of the on-surface synthesis, including organic synthesis of the precursor molecules. Besides the two main proposers, four other research groups are already interested in using this instrument and strongly support this proposal. All six research groups are strongly connected and have collaborations due to the proposed Collaborative Research Centre "Chemistry of Synthetic Two-Dimensional Materials". However, other interested research groups are highly welcome to use the instrument. The research focus of the proposed instrument is the on-surface synthesis of novel two-dimensional polymers (including two-dimensional organic covalent polymers and metal-organic polymers), graphene nanoribbons, polycyclic aromatic hydrocarbons as well as molecular switches, machines and logic gates for electronics. Besides the synthesis and corresponding visualization via low-temperature scanning tunneling – and atomic force microscope, the investigations of the electronic properties, such as band gap or energy levels of the orbital frontiers, will be investigated by scanning tunnel spectroscopy. A further focus of the proposed device will be the development of novel reaction methodologies to form long graphene nanoribbons and highly crystalline two-dimensional polymers on the surface.
