Novel self-organization molecules, n-mercapto-alkyl benzo-annelated tetrathiafulvalenes (BTTF), have been synthesized. Exposure of polycrystalline Au and oriented crystalline Au (111) surfaces to organic solution of the novel BTTF derivatives in high magnetic field results in the binding of the derivatives to Au and the formation of highly-oriented self-assembled monolayers (SAMs) with redox active tetrahia-fulvalene (TTF) unit. The electrochemical properties were confirmed in the monolayer state. A comparison between SAMs on polycrystalline Au having a rough surface andon oriented crystalline Au (111) having a flat surface suggested that the well-oriented alkyl-chain layers in the SAMs could be blockade for the electron transfer between the TTF unit and the Au substrate.
