We achieve locally guided growth of organic semiconductor nanostructures by utilising direction-dependent stabilities of supramolecular chains. For example, linear chains are self-assembled from Quinacridone molecules via Hydrogen bonds (H-bonds). Force-Field Calculations of supramolecular binding energies for different directions revealed that such chains are most resistant against tip-sample interactions if the stress, resulting from these interactions, is induced parallel to the H-bond direction.
As a consequence, our approach is based on the adjustment of the degree and direction of the induced stress. By setting the tip-sample distance to a degree which only allows the growth of wire nuclei aligned with their H-bond direction nearly parallel to the stress direction (nanomanipulation direction or fast scan direction respectively), orientation selective growth can be achieved as non-parallel aligned wire nuclei are less resistant against the stress and thus are being desorbed and replaced.
