Extended hydrogen–bonded networks are formed by P. Rahe et al. after deposition of terephthalic and trimesic acid on the insulating calcite CaCO 3 (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 CaCO 3 (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.
