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.
