Stacking phenomenon of self-assembled monolayers and bilayers of thioalkyl-substituted tetrathiafulvalene
The self-assembled monolayer and bilayer of tetrakis (octadecylthio)tetrathiafulvalene (TODT-TTF) on highly orientated pyrolytic graphite (HOPG) surface were studied by scanning tunneling microscope (STM). Direct observation of the dimer of TODT-TTF formed by pi-pi interaction was achieved.
