Highly ordered monolayers of macrocyclic oligothiophene C[12]T (see Figure) can be used as veritable templates to epitaxially grow 3D nanoarchitectures with C60-fullerenes. Due to submolecularly resolved STM images, 1:1 complexes consisting of a ring-shaped p-type semiconductor (C[12]T) and a spherical n-type semiconductor (C60) can be investigated in terms of dynamics and complexation sites.
