Abstract

1,7-Diadamantanethioperylene-3,4:9,10-tetracarboxylic diimide, (Ad-S)2–PTCDI, adsorbed on Au(111) from solution was investigated by scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). (Ad-S)2–PTCDI forms a well-ordered monolayer whose structure is described by a (2√63 × √19)R19.1° chiral unit cell containing four molecules. Codeposition of (Ad-S)2–PTCDI with 1,3,5-triazine-2,4,6-triamine (melamine) yields a honeycomb network whose (7√3 × 7√3)R30° unit cell is identical to the unsubstituted PTCDI/melamine analogue. The effect of the adamantyl thioether moieties on the adsorption of guest molecules is investigated using adamantane thiol and C60. While the thioether units do not affect the packing of adamantane thiol molecules a pronounced influence is seen in the case of fullerene. Pore modification involving different combinations of enantiomers of (Ad-S)2–PTCDI give rise to distinctly different arrangements of C60 molecules. The diversity of patterns is further increased by the presence of unsubstituted PTCDI molecules.
