The objective of the proposed studies is the investigation and deliberate steering of supramolecular self-organization using complex molecules at well-defined substrates for the fabrication of functional nanostructures. The underlying molecular self-assembly will exploit different non-covalent interactions (metal coordination, hydrogen bonding, donor-acceptor interactions) which are directly characterized at the single-molecule level by means of scanning tunneling microscopy techniques. In particular, we shall employ appropriately designed molecular building blocks for the modular construction of functional architectures and nanostructures from organic species and metal atoms at surfaces. Alternatively, the fabrication of nanostructures across multiple length scales will be pursued by directing the self-assembly by pre-patterned motifs. The envisaged functionalities comprise molecular magnetism, selective host-guest interactions and new concepts of molecular motion and conformational changes. In addition, the self-assembly of biomolecules will be investigated. Theoretical model calculations will be performed in order to obtain a comprehensive understanding of molecular recognition and self-assembly at surfaces and to guide the development of suitable design strategies towards novel supramolecular nanosystems. The synergetic combination of expertise in supramolecular chemistry, nanoscale physical science and computational modeling will open new pathways for the fabrication of functional molecular nanosystems.

这项研究的目的是研究和刻意引导超分子自组织，利用复杂分子在定义明确的底物上制造功能纳米结构。潜在的分子自组装将利用不同的非共价相互作用(金属配位、氢键、供体-受体相互作用)，这些相互作用通过扫描隧道显微镜技术在单分子水平上直接表征。特别是，我们将利用适当设计的分子构建块，以有机物种和表面的金属原子为基础，模块化构建功能结构和纳米结构。或者，将通过预先图案化的图案引导自组装来追求跨越多个长度尺度的纳米结构的制造。设想的功能包括分子磁性、选择性主客体相互作用以及分子运动和构象变化的新概念。此外，还将研究生物分子的自组装。将进行理论模型计算，以全面了解分子在表面的识别和自组装，并指导开发适合于新型超分子纳米系统的设计策略。超分子化学、纳米级物理科学和计算模型方面的专业知识的协同结合将为功能分子纳米系统的制造开辟新的途径。
