Two “face‐on” phases and one “edge‐on” lamellar phase comprised of self‐assembled structures of phthalocyanines have been visualized by scanning tunneling microscopy (STM) at the gel–graphite interface. The switching between the phases can be stimulated with the microscope tip with a resolution on the molecular scale. The STM image shows the manipulated area consisting of π–π stacked phthalocyanines forming the lamellar phase, which is embedded in a hexagonally packed “face‐on” phase.
