The packing of organic molecules in three dimensional space is practically impossible to predict, while the situation at interfaces is considerably more straightforward given certain design criteria. However, in this presentation we shall show that simply modifying the shape of a molecule as well as the chirality of the component parts can have a dramatic effect on the outcome of adsorption. In particular, a homologous series of aromatic molecules substituted with lactic acid on one side and alkyl chains on the other display a plethora of intriguing phases at the graphite-liquid interface. On the other hand, the consitution of aromatic molecules has a direct consequence on their chemistry at a metal surface. The presentation will put the results obtained into the context of the supramolecular chemistry of molecules in two and three diemnsional systems.
