Supramolecular chemistry provides a useful tool for the design of nanostructures following bottom-up principles. Recent studies have revealed that self-assemblies of molecular building blocks at surfaces can be used for nanopatterning or surface templating.
STM investigations of zinc-phthalocyanine (ZnPc), half-fluorinated and half-chlorinated phthalocyanines (ZnPcF8 and ZnPcCl8) deposited on Ag(111) will be presented. ZnPcF8 and ZnPcCl8 are obtained by the substitution of half of the sixteen surrounding hydrogen atoms of ZnPc by halogen atoms. These molecules was designed in order to create hydrogen bonds between molecules which provides both high selective and directional bonds.
We’ll see how such modification can be used to tune molecule-molecule as well as molecule-substrate interactions in order to control the properties and the architecture of such nanostructures.
