O 20: Focus Session: Molecular Nanostructures on Surfaces: On-Surface Synthesis and Single-Molecule Manipulation I

Tuesday, March 19, 2024, 10:30–13:00, HE 101

Surface-confined molecular nanostructures hold promise for applications in nanoscale (opto-) electronics, spintronics, solar cells, energy storage, and more. The bottom-up fabrication involves molecular self-assembly using non-covalent interactions, covalent on-surface synthesis, or direct molecule manipulation. Self-assembly yields highly ordered nanostructures influenced by non-covalent and adsorbate-substrate interactions, thermodynamics, and kinetics. Covalent on-surface synthesis on metallic, semi-conducting, or insulating surfaces offers new routes for complex low-dimensional nanostructures with unique properties. Direct manipulation with a scanning probe microscope enables unprecedented chemical transformations. The Focus Session provides a platform to discuss current trends in these interconnected fields from diverse experimental and theoretical perspectives. It addresses recent advancements in on-surface synthesis, manipulation, characterization, and comprehension of complex molecular architectures.
