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.
