Event Details

Manfred Buck of the University of St Andrews joins the Chemistry Department for a seminar on nanostructures. Also available on Teams.

Spontaneous assembly of functionalised aromatic molecules on surfaces has been widely employed, ranging from the formation of extended networks of flat lying molecules linked by supramolecular or covalent bonding to layers of densely packed, upright orientated molecules, commonly referred to as self-assembled monolayers (SAMs). Networks and SAMs are complementary in various ways. As a bottom-up approach, the former enable ultraprecise templating but are limited to regular structures and difficult to functionalise. In contrast, SAMs provide flexibility in the functionalisation of surfaces, which makes them attractive for area selective deposition, but patterning relies on top-down strategies. Focusing on processes at the solid/liquid interface including the electrochemical one, the talk will discuss opportunities and challenges of molecule based bottom-up and top-down strategies for the generation of low dimensional structures.
