“…Compared to the adsorbate free Au(111) surface 13,21 , there is, however, a significant difference in the periodicity of the structure. As known from other studies 22,23 the reconstructed surface can be substantially altered by molecular adsorbates. In the present case an average value of about 70 Å is measured, i.e., a larger 24×3 structure compared to the 22×3 unit cell of the clean Au(111) surface.…”

Bestowing structure upon the pores of a supramolecular network

et al. 2014

Trigonal molecules compartmentalise the pores of a honeycomb network of 3,4:9,10-tetracarboxylic diimide (PTCDI) and 1,3,5-triazine-2,4,6-triamine (melamine). Extending the 1,3,5-tri(phenylene-ethynylene)benzene core by a phenyl group allows for a well-defined accommodation of the molecule into two symmetry equivalent positions in the pore. The corresponding styryl or phenylene-ethynylene derivatives exceed the pore size and, thus, impede pore modification.

“…Figure 2 shows an STM topography of such a triple layer NaCl island on Au(111). In the left part of the figure (dark contrast) the herringbone reconstruction of the bare gold surface is clearly visible 25,26,33,34 . In the outermost atomic layer of the Au(111) surface, 23 atoms are arranged over 22 bulk lattice sites, resulting in a contraction of the interatomic distance from 0.289 nm (bulk value) to 0.275 nm along the 1110 direction.…”

The growth of fullerene nanocrystals, composed of only C(60), only C(70), or a mixture of both fullerenes, has been investigated by scanning tunneling microscopy (STM). The nanocrystals, formed on a NaCl ultrathin layer partially covering a Au(111) surface, have characteristic truncated-triangular or hexagonal shapes, with lateral size up to 100 nm and a typical height of two to four molecular layers. This growth mode differs considerably from the ones observed on metallic surfaces. STM images with biasdependent submolecular resolution reveal the spatial distribution of the electronic density originating from the molecular orbitals. A comparison of the experimental results with first-principles density functional theory calculations allows us to unambiguously determine the orientation and the nature of individual fullerene molecules in the surface layer of the nanocrystals.

The structural properties and the interaction strength of naphtho[2,3-a]pyrene (NP), a promising multifunctional organic material for optoelectronic devices, has been studied on Au(111) by means of scanning tunnelling microscopy. The perturbation of the native herringbone reconstruction of the pristine Au(111) surface was used to assess the interaction strength of the organic film with the surface. It was found that a moderate temperature treatment (500 K) of the NP film led to a new equilibrium structure, which dramatically perturbed the herringbone reconstruction. Our data suggest that organic-metal interfaces studied at room temperature or lower do not necessarily reflect the true equilibrium structures of the organic films, which are important in understanding the associated properties of organic thin film electronic devices. Interpretation of the selfassembled NP structure on Au (111) is discussed in conjunction with STM tip induced imaging effects which appear prevalent on these complex organic/metal interfaces.
