Abstract |
Self-assembled monolayers (SAMs) formed by organic molecules containing sulfur headgroup on metal surfaces have drawn much attention because of its ability to control the physical and chemical properties of solid surface. In nano and biotechnology, symmetric or unsymmetric dialkyl disulfides have been often used for the fabrication of molecular thin fillmes to adjusting the degree of phase segregation and preferential adsorption. However, there have been no reports on the domain formation and strcuture of unsymmetric adamantyl hexyl disulfide (AHDS) and adamantyl decyl disulfide (ADDS) containing adamantyl group with aliphatic 3D carbon cage structure and normal alkyl chains on Au(111) from the molecular-scale viewpoint to date. In this study, we have monitored the formation and domain strcuture of AHDS and ADDS SAMs on Au(111) using scanning tunneling microscopy. We revealed the unique ordered domains of these SAMs on Au(111), which have never been observed from each single component SAMs from 1-adamantanethiol, 1-hexanethiol and 1-decanethiol using molecular-scale scanning tunneling microscopy. |
