These structures indicate several important components of this molecule in determining and enforcing an ordered packing motif that may be generalizable to other supramolecular design schemes. In the monolayer structure, the geometry of the amino group enforces a motif in which part of the molecule lies upon the graphite surface and one of the alkyl chains extends away from the surface. This extended chain is a structure director for the formation of bilayer structures. The apparent thickness and stability of the bilayer structures are shown to be dependent on the presence of water or other admixtures, suggesting intercalation of small, polar molecules into this bilayer.}, number={11}, journal={Langmuir}, author={Gorman, C.

However, this process could be tempered by moderating the concentration of H2S in the vapor above the gold. When corrosion was minimized, corroded regions were observed to exist predominantly at step edges. At a sufficiently low concentration of H2S, linear triple-row structures were observed. These are not the same as those observed when aqueous sulfide was reacted with a gold surface. A model that accounts for all the features of the adlayer structure is presented that involves a packing density of hydrosulfide groups of 28.5 A2/molecule, which is lower than that found in a √3 x √3 R30 overlayer (21.5 A2/molecule) found for long-chain alkanethiolate self-assembled monolayers on Au(111).}, number={18}, journal={LANGMUIR}, author={Touzov, I and Gorman, CB}, year={1997}, month={Sep}, pages={4850–4854} }

Such samples could be transformed from this structure to a c(4×2) superlattice under the influence of a scanning tunneling microscope (STM) tip. These images were comparable to those obtained by thermally annealing the sample. Using an atomic force microscope tip in friction force mode (FFM), the c(4×2) superlattice could be observed on thermally annealed samples, but pressing upon the sample with a moderate tip load (as high as 80 nN) did not induce this structure. Comparative analysis of the results obtained by these two techniques suggests that this transformation occurred as the result of the tip pressing upon the surface. In addition to this final structure, intermediate structures were observed during these tip-induced transformations. The STM-induced transformation revealed an intermediate structure of p2 symmetry.
