Two-dimensional self-assembly of 1-octanol molecules on a graphite surface is investigated using scanning tunneling microscopy (STM) at the solid/liquid interface. STM images reveal that this molecule self-assembles into a compact hydrogen-bonded herringbone nanoarchitecture. Molecules are preferentially arranged in a head-to-head and tail-to-tail fashion. A Moire pattern appears in the STM images when the 1-octanol layer is covering the graphite surface. The large Moire stripes are perpendicular to the 1-octanol lamellae. Interpretation of the STM images suggests that the Moire periodicity is governed by the electronic properties of the graphite surface and the 1-octanol layer periodicity.
