This Minireview focuses exclusively on work with scanning tunneling microscopy to study the self‐assembled multilayer films (SAMTs) of organic molecules. The π‐conjugated organic molecules form different structures within different monolayers on various substrates. The interplay between molecule–substrate and intermolecular interactions plays a key role in determining the stacking mode of organic multilayer films. Different substrates strongly influence the organic‐film growth and electronic properties of the organic molecules. Geometric and electronic structures of SAMTs are important factors that may determine device performance. In addition to the inorganic interface, this Minireview addresses the organic–organic interface. Homo‐ and hetero‐SAMTs of organic molecules are also considered. The subtle interplay between structural and electronic characteristics, on one hand, and functionality and reactivity, on the other hand, are highlighted.
