Templating: Substrate Templating upon Self‐Assembly of Hydrogen‐Bonded Molecular Networks on an Insulating Surface (Small 19/2012)

Extended hydrogen–bonded networks are formed by P. Rahe et al. after deposition of terephthalic and trimesic acid on the insulating calcite CaCO3(1014) surface. The self-assembled structures are stable at room temperature and no molecular dewetting is observed. A combined model of the molecular superstructures on the CaCO3(1014) surface. The left inset presents molecular double chains of terephthalic acid molecules, while the right depicts nearly hexagonal trimesic acid molecules. Single molecules are resolved in both images. A detailed analysis of the molecular structures on page 2969 reveals the significant influence of the underlying substrate, clearly indicating a substantial templating effect of the surface on the resulting molecular networks.
