That the alignment of dipolar organic molecules in any direction can be achieved in situ with oblique organic molecular beam deposition was demonstrated in the previous paper. Here is proposed a growth mechanism to explain the observed in‐plane ordering that gives rise to these dipolar supramolecular assemblies. It is concluded that the preferential alignment of the molecules is due to the combination of shape and bonding features of the molecules, together with kinetic factors such as directional hydrogen bonding, and self‐shadowing and self‐correcting effects.
