讲座摘要：

     The presentation will discuss recent advancements and challenges in the on-surface synthesis of extended covalent nanostructures. A particularly important and widespread coupling reaction is the so called surface-assisted Ullmann coupling, where halogenated precursors recombine by forming interlinking C-C bonds after the thermally activated dehalogenation on the surface. Here it is particularly instructive to focus on differences between seemingly very comparable metal surfaces, i.e. Au(111) vs. Ag(111). On the other hand, even though quite challenging, the tool box of on-surface synthesis is continuously enlarged by newly discovered or developed coupling reactions. In most cases these are inspired by solution chemistry, but transferring the coupling reactions onto surfaces can have implications that reach significantly beyond imposed geometrical constraints. Exemplarily, the thermally induced surface chemistry of a three-fold thiol functionalized monomer on Au(111) will be discussed.
