This presentation will review our recent studies of the role of hydrogen bonding and other supramolecular interactions in controlling self-assembly of functional semiconducting molecules. Using a combination of STM, AFM, X-ray crystallography and DFT calculations, we explore the complex interplay of intramolecular, molecule-molecule and molecules-surface interactions in defining the supramolecular structure at the interface. The discussed case-studies will include hydrogen-bonding assembly of naphthalenediimides (NDIs)n in monolayersand thin films on conducting and insulating surfaces, the effect of aromatic rings in diketopyrrolopyrrole oligomers, and assembly of fullerene and its derivatives on thiol-based monolayers.
