Self-Assembly at the Liquid/Solid Interface: Playing on the Nanoscale and Taming Molecules — •Manfred Buck — University of St Andrews, St Andrews, United Kingdom

The combination of intrinsic atomic precision with structural and functional versatility, and spontaneous assembly on surfaces make organic molecules essential components of a developing toolbox aimed at the routine access to the bottom end of the nanoscale. With options ranging from two-dimensional porous networks of flat lying to densely packed layers of upright standing molecules, thermodynamically and kinetically controlled processes at the liquid-solid interface (including the electrochemical interface) offer a rich playground for surface functionalisation, templating, and patterning on the ultrasmall scale. However, progress on the route to ultimately functional nanostructures will be critically dependent on how well we can control the energy landscape of molecular assemblies. This comprises both static and dynamic aspects and involves the spectrum of intermolecular and molecule-substrate interactions, diffusion processes, and boundary conditions imposed by a highly confined space. Presenting illustrative examples of our work which range from hierarchical assembly based on supramolecular networks to molecular monolayers involving metal-organic coordination, the talk will provide a critical account of achievements and challenges ahead.
