Scanning Probe Studies of Porphyrin Assemblies and Their Supramolecular Manipulation at a Solid–Liquid Interface

Dynamic self‐assembly and metal–ligand coordination processes of porphyrin hexamers on a solid–liquid interface have been visualized with scanning tunneling microscopy. The organization of these hexamers into stable and highly organized arrays of “edge‐on” or “face‐on” oriented molecules can be controlled by the addition of different ditopic axial ligands (see Figure).
