Exploring Molecular Assembly at Surfaces

The adsorption and self–assembly of organic molecules at surfaces has recently been investigated extensively, both because of the fundamental interest and for prospective applications in nanoelectronics and organic electronics. It is now well established that molecule–molecule and molecule–substrate interactions can be tuned by appropriate choice of substrate material and symmetry. Upon molecular adsorption, surfaces typically do not behave as static templates, but often rearrange to accommodate different molecular species. We discuss recent experiments using Scanning Tunnelling Microscopy and complementary surface sensitive techniques, providing new insights into fundamental processes ranging from the formation of ordered patterns driven by non-covalent bonds to the realization of robust structured held together by covalent bonds. In particular, we will focus on recent advances in using the substrate as catalyst for surface confined polymerization reactions, emphasizing Ullmann coupling as key example. Speaker(s): Professor Federico Rosei, Agenda: The talk will begin at 2pm and conclude at 3pm, followed by a 10 minute Q&A session. Light refreshments will be provided.
