By artificially modifying the potential energy surface that governs the self-assembly of a 2D metallorganic crystal of iron phthalocyanines, we show that it is possible to switch from substrate- to laterallydriven regimes. By exploiting the capability of an ultra-thin alumina film to host metallic nanoparticle seeds, we achieve the tunability of the process, ultimately determined by the average nanocluster size. Long-range self-assembly mechanisms are attractive for applications in the synthesis of novel nanotechnological devices, and our work provides an original contribution to this field.
