                      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.},
