abstract = {The synthesis, adsorption behavior, surface structure, and
the charge transport properties of a persulfurated coronene
asterisk with a 3D-polyaromatic system, namely
dodecakis(phenylthio) coronene (DPTC), deposited on
HOPG(0001) and Au(111) surfaces, are investigated by means
of scanning tunneling microscopy (STM) and spectroscopy
(STS). DPTC molecules adsorbed on HOPG(0001) show an orbital
mediated tunneling through mainly undisturbed frontier
molecular states. DPTC molecules self-assemble on Au(111)
into a highly ordered p-stacked columnar "edge-on pattern.
The columnar stacking is a gold surface mediated process, as
ascertained by fluorescence correlation spectroscopy (FCS).
DPTC was monomeric in the precursor solution before
assembly. The tunneling spectra of ordered DPTC stacks on
Au(111) show an energetic splitting of the frontier
molecular states, indicating orbital overlap and
supramolecular pi pi interactions of adjacent molecules.
DPTCs are sufficiently flexible to facilitate dense 1D
stacks. The multiple aryl-sulfur bonds play a dominant role
in the modulation of the self-assembly properties of the
coronenes which in turn affect their electronic properties.
Our results encourage further applications in dendrimer
chemistry toward molecular electronics, by using the
functionalized coronene core and its multidirectional 3D
properties.},
