On the other hand, alkanedithiol SAMs are experimentally and theoretically less studied, and especially information on the tilt angles of the ligands are rare. We study structural parameters like the ligand coverage, the tilt angle and the adsorption position of singly deprotonated dithiol ligands on Au(111) surfaces and compare them to experimental and theoretical data on alkanemonothiols from the literature. In the next step, sandwich structures are constructed based on SAM simulations for dithiolate and based on information from the literature for monothiolate ligands of different chain lengths, and the preferred surfaceto-surface distances are extracted and compared to experimentally measured interparticle distances in GNP assemblies.
