I will describe recent results concerning molecular reaction and organization on surfaces as studied by STM and XPS in collaboration with chemical synthesis and DFT modeling. Within the field on on-surface synthesis, we have explored the prototypical �click�-reaction of azide-alkyne cycloaddition for reactants adsorbed on a Cu(111) surface under UHV conditions [1]. The reaction is shown to proceed and azide decomposition is identified as the factor limiting the yield. Secondly, we have identified a novel metal coordination network formed through dehydrogenation of tetrahydroxybenzene [2]. Finally, we have investigated a model system of binary conformational switches based on a series of Oligo-Naphthalene Ethynylenes [3]. Using time-resolved STM we have visualized the dynamics of conformational switching and quantified the selection of conformational states in self-assembled structures.[1]: F. Bebensee, K. V.
