Examples of Molecular Self‐Assembly at Surfaces

The self‐assembly of molecules at surfaces can be caused by a range of physical mechanisms. Assembly can be driven by intermolecular forces, or molecule‐surface forces, or both; it can result in structures that are in equilibrium or that are kinetically trapped. Here we review examples of self‐assembly at surfaces focusing on a physical understanding of what causes patterns seen in experiment. Some apparently disparate systems can be described in similar physical terms, indicating that simple factors – such as the geometry and energy scale of intermolecular binding – are key to understanding the self‐assembly of those systems.
