  Abstract: The growth and ordering of   copper-substituted and free-base   2,9,16,23-tetra-tert-butyl-phthalocyanine on a graphite surface   at the solution−solid interface can be controlled by solvent   choice. One-dimensional ordered molecular layers having the   molecular plane lying parallel to the graphite substrate were   obtained at the octylbenzene solution−graphite interface at room   temperature. The arrangement was changed to two different   two-dimensionally ordered lattices by replacing the solvent with   bromine-substituted octylbenzenes. The free base and copper   complexes gave the same surface structures in octylbenzene and in   1-bromo-4-n-octylbenzene, indicating that the central metal ion   was not playing a critical role in determining the surface   structure. These structures were determined from the analysis of   the images with scanning tunneling microscopy.
