The unique electrochemical and photophysical properties of porphyrin and [60]fullerene compounds makes them promising candidates for the construction of two- and three-dimensional organic-based materials. An important question is how pristine C60 and self-assembled monolayer of porphyrin arrays will organize on surfaces. Self-assembly of electron-rich flat aromatic molecules such as porphyrins shall enable the selective formation of electron donating monolayer, which can be covered by pristine C60. The chromophore interaction between the electron donor (porphyrin) and acceptor (C60) should enhance a supramolecular multilayer structure. Herein, we report first Scanning-Tunneling-Microscopy investigations of the behaviour of several porphyrin derivatives on metal surfaces wherein single porphyrin molecules are forcefully arranged in self-assembled monolayer. The specific properties of the single porphyrin derivatives make such molecularly modified surfaces suitable candidates for patterned surfaces to allocate fullerenes. Consequently, first nanostructures based on the interaction of the fabricated porphyrin-based assemblies with fullerene molecules will be presented.
