%X The self-assembly
of thienophenanthrene derivative with V-shape
conjugated core and four tetradecanoxyl chains (TPTD-Nap) at different
solution concentrations has been investigated at the liquid–solid
interface by scanning tunneling microscopy. n-Tetradecane
was chosen as the solvent because its alkyl chain is commensurate
with the length of the molecular side chains. At saturated concentration,
TPTD-Nap forms a linear pattern with long-range disorder and short-range
order. As the concentration decreases, a highly ordered linear structure
is observed. At low concentrations, TPTD-Nap molecules self-assemble
into three types of nanostructures with reduced packing density because n-tetradecane molecules participate in the self-assembled
process by the coadsorption at different levels. The most remarkable
feature of the TPTD-Nap arrangements is the self-adaption of symmetric
V-shape cores as well as the alkyl chain-length of the molecule and
solvent. The former contributes to fabricate the backbone of the nanostructures,
and the latter determines the self-assembled polymorphism by the coadsorption.
