Materials with a pre‐programmed order at the supramolecular level can be engineered with a sub‐nanometer precision making use of reversible non‐ covalent interactions. The intrinsic ability of supramolecular materials to recognize and exchange their constituents makes them constitutionally dynamic materials. The tailoring of the materials properties relies on the full control over the self‐assembly behavior of molecular modules exposing recognition sites and incorporating functional units. In this review we focus on three classes of weak‐interactions to form complex 2D architectures starting from properly designed molecular modules: van der Waals, metallo‐ligand and hydrogen bonding. Scanning tunneling microscopy studies will provide evidence with a sub‐nanometer resolution, on the formation of responsive multicomponent architectures with controlled geometries and properties. Such endeavor enriches the scientist capability of generating more and more complex smart materials featuring controlled functions and unprecedented properties.
