2-Mercaptopyrimidine (2MPy) forms a two-dimensional planar lattice on Au(111). This structure is able to intercalate guestmolecules such as the oligopyridines. To test the ability of the 2MPy lattice as a host able to intercalate a variety of moleculesregardless of their geometry and electronic structures, some arenes and polyenes were analyzed as possible guests. Benzene,naphthalene, azulene, phenanthrene, anthracene, biphenyl, uorobenzene and durene were selected to coadsorb with 2MPy on thesurfaces. The experimental data show that the arenes and polyenes selected coadsorb with 2MPy on Au(11) under dened ex-perimental conditions, forming a mixed layer with stoichiometry of 2:1 in thiol:guest. The STM contrast observed for the guestmolecules is compared to the experimental and theoretical results already published.. 2002 Elsevier Science B.V. All rights re-served.
