Investigation of the Epitaxial Growth of Octamethylene-Tetrathiafulvalene (OMTTF) on Substrates of Different Chemical Reactivity

Investigation of the Epitaxial Growth of Octamethylene-Tetrathiafulvalene (OMTTF) on Substrates of Different Chemical Reactivity

“…On the Ag(100) substrate the misfit between the monolayer and the normal structure is too large. This results in a clusterlike growth of the multilayer [16] (see Fig. 10).…”

“…[16] Here only a short summary of the relevant results will be presented. Figure 2 shows a normal-incidence LEED image of an OMTTF monolayer on Ag(100 Monolayers of the organic donor OMTTF (octamethylene-tetrathiafulvalene) were grown on a Ag(100) substrate and on the iodine c(22) superstructure on Ag(100) by organic molecular beam deposition (OMBD) under ultra high vacuum (UHV) conditions.…”

Perspectives on Thin Molecular Organic Films

“…[102] Reconstructed surfaces are usually perturbed by the fullerene molecules, as has been evidenced by their interactions with Ge(111)-c(2 8), where Ge adatom rows are shifted, [103] and in Au (110)-p(1 2), where a Au(110)-p(6 5) superstructure is induced. [104] Systematic STM studies of planar molecules such as perylene on inorganic substrates have been reported, [105] as well as the chemisorption of aniline on Si(100)-(2 1), [106] perylenetetracarboxylicdianhydride (PTCDA) on HOPG, [107] acetylene on Pd (111), [108] and octamethylene-TTF (OMTTF) on Ag(100), [109] to mention just a few. Diffraction at grazing angles with synchrotron radiation enables the in situ characterization of the dynamical formation of the interface, as reported recently for alkanethiols SAMs on Au (111) substrates.…”
