Steering Self‐Assembly of Three‐Dimensional Iptycenes on Au (111) by Tuning Molecule‐Surface Interactions

Abstract: Self‐assembly of three‐dimensional molecules is scarcely studied on surfaces. Their modes of adsorption can exhibit far greater variability compared to (nearly) planar molecules that adsorb mostly flat on surfaces. This additional degree of freedom can have decisive consequences for the expression of intermolecular binding motifs, hence the formation of supramolecular structures. The determining molecule‐surface interactions can be widely tuned, thereby providing a new powerful lever for crystal engineering in two dimensions. Here, we study the self‐assembly of triptycene derivatives with anthracene blades on Au (111) by Scanning Tunneling Microscopy, Near Edge X‐ray Absorption Fine Structure and Density Functional Theory. The impact of molecule‐surface interactions was experimentally tested by comparing pristine with iodine‐passivated Au (111) surfaces. Thereby, we observed a fundamental change of the adsorption mode that triggered self‐assembly of an entirely different structure.
