“…When adjacent rows scatter in phase, very strong diffraction spots perpendicular to the rows are to be expected. Our results are completely consistent with, and thus reconfirm, the structure found in STM studies for BDA on Au(111) [43,19,108]: elongated domains, or needles, consisting of parallel chains of molecules. The chains aggregate side by side, and are stabilized by van der Waals forces.…”

“…6.5(b). The molecules in this structure are arranged similar to BDA structures observed on Au(111) (see Chapter 7) or HOPG [43,108]. In the latter structures, the molecules interact through dimer hydrogen bonds between the protonated carboxylic acid groups.…”

“…7.2. The molecules arrange in a close packed structure, as already observed in STM in other studies [43,19,108]. In the grammar of molecular epitaxy [97], this superstructure corresponds to a coincidence-IA "point-on-line" (POL) overlayer.…”

“…A direct interaction between the carboxylate groups is not possible. STM studies on the adsorption of BDA [43,19,108] and of the similar terephthalic-acid (TPA) on Au(111) [13] reported close-packed structures, with molecular chains located side by side. This structure is typical for the carboxylic-acid head to tail bonding as the main intermolecular interaction motif and the same interaction is also observed in bulk crystal modifications of TPA [116].…”

“…The latter depends on the number of carboxylic-acid functional groups, and their respective positions. For example, linear and symmetric benzoic-acids often assemble in close-packed rows forming carboxylic-dimer head to tail bonds [13,18,43,110,108,44], while benzoic-acids with a threefold symmetry form honeycomb networks [16,10,20].…”

Work Function Maps and Surface Topography Characterization of Nitroaromatic-Ended Dendron Films on Graphite

et al. 2013

View full text Add to dashboard Cite

Surface topography and work function maps were simultaneously obtained for carbon surfaces modified by a dendritic molecule: 3,5-Bis (3,5-dinitrobenzoylamino) benzoic acid. The dendrons were spontaneously assembled onto highly ordered pyrolytic graphite samples, exhibiting an increase in the surface potential. This fact is consistent with the incorporation of an electron-acceptor functional group that remains electroactive on the surface.

Role of Phase Stabilization and Surface Orientation in 4,4′-Biphenyl-Dicarboxylic Acid Self-Assembly and Transformation on Silver Substrates

Molecular functionalization of nanoparticles and metallic substrates can be used to tune their properties for specific applications. However, polycrystalline substrates and nanoparticles exhibit surface planes with distinct crystallographic orientations. Therefore, the development of reliable strategies for molecular functionalization requires knowledge of the role of the surface plane orientation in the growth kinetics, structure, and properties of the molecular layer. Here, we apply a combination of low-energy electron microscopy and diffraction, scanning tunneling microscopy, and photoelectron spectroscopy to investigate the self-assembly of 4,4′-biphenyl-dicarboxylic acid (BDA) on Ag(111) and critically discuss the difference to Ag(100). The structural motifs for intact and fully deprotonated BDA are similar on both surfaces, however, the intermediate phases comprising partially deprotonated BDA differ in structure and chemical composition. A real-time view of the phase transformations enables us to present a generalized picture of the phase transformations between the self-assembled molecular phases on the surfaces and underline important features such as the phase stabilization of the chemical composition and the mechanism of the related burst transformation. The influence of the substrate orientation on the structure of molecular layers and phase transformations provides the necessary background for developing functionalization strategies of the substrates displaying multiple surface planes and kinetic models for the growth near thermodynamic equilibrium.
