On-surface azide-alkyne click chemistry and a novel metal-organic network based on Cu adatom trimers — •Trolle Linderoth — Interdisciplinary Nanoscience Center (iNANO) and Department of Physics and Astronomy, Aarhus University, Denmark

Molecular nanostructures on solid surfaces are central to achieve advanced functional surfaces. Covalent synthesis with reactants adsorbed on surfaces has therefore been the focus of intense recent interest. In this context there is a need to identify suitable chemical reactions that will proceed under Ultra High Vacuum conditions. Early work in this direction from our group focused on the condensation reaction between aldehydes and amines to form imines [1-3]. Here, it was shown that the connectivity in two-dimensional surface polymeric networks could be controlled by kinetic parameters of the preparation procedure. More recently, we have explored the prototypical click-chemistry reaction of 1,3-dipolar Huisgen cycloaddition between azides and terminal alkynes to form a triazole product for reactants adsorbed on a Cu(111) surface (CuAAC reaction) [2]. Finally we have investigated the on-surface dehydrogenation reaction for tetra-hydroxy-benzene (THB) which enables formation of a novel metal-coordination network containing trimeric Cu-adatom clusters [3].
