The self-assembly of 1,2,3,4-tetrahydronaph-thalene molecules is investigated using scanning tunneling microscopy (STM) at the solid/liquid interface. STM reveals that the molecule self-assembles into a chiral close-packed herringbone structure and a chiral porous pinwheel nano-architecture at room temperature on graphite. The two networks are equally distributed on the surface, and the two enantiomeric molecular arrangements of the two structures are observed. Variation of the molecule−surface epitaxial relationship suggests that the pinwheel arrangement favors molecule− surface interactions, whereas the herringbone arrangement favors intermolecular interactions.
