Molecular self-assembly at surfaces gives a versatile framework to organize/pattern functional materials in technologically relevant environment (thin films) and with unprecedented sub-nm precision. Numerous 2D architectures with a remarkable molecular-level control have already been demonstrated. The next big step for the field will be bridging the gap between this �2D crystal engineering� and actual applications in materials science and engineering.I will present our first humble moves in this direction in two examples. First, I will demonstrate the application of 2D molecular networks to template the epitaxial growth of metal nanoparticles at solid-liquid interface. I will show how in-registry interactions between the matching length alkyl chains can guide the growth of nanoparticle superlattices with non-centrosymmetric unit cell. Second, I will update on our continuing project in creating 2D conjugated polymers with �onmiconjugated� building blocks. I will highlight the challenges posed by the (unintuitive) chemistry of metal surfaces and discuss the electronic properties of the obtained 2D polymers.
