Function follows form: exploring two-dimensional supramolecular assembly at surfaces.

Two-dimensional surface structures formed by organic self-assembly offer an efficient route to bottom-up assembly of tailored nanostructures. Organic building blocks are especially interesting because of the wide variety of structures and properties that can be "built-in" at the synthesis stage. Well-controlled studies of these systems under ultrahigh vacuum conditions allow a careful look at the fundamental properties and relevant kinetic growth limitations. Further work will develop our understanding of the functionality of the systems and their potential use in technological applications.
