A unique construction process for supramolecular assemblies in the 10 - 100 nm length scale that are connected to electrodes and act as (opto)electronic components is proposed. This unexplored field of research is proposed to be called supramolecular electronics. For the fabrication of these supramolecular electronic devices, π-conjugated oligomers, that is, (chiral) oligo(phenylenevinylene)s will be synthesized, which self-assemble in a controlled fashion into (helical) wires. In these stacks energy traps will be incorporated to investigate fundamental issues like light harvesting, exciton diffusion length and energy transfer processes within the nanometer dimensions. Additionally electron acceptors will be built-in to obtain electron transfer and to convert light into a chemical reaction or electricity. These structures in solution will be transformed to a solid support and sandwiched between electrodes. Therefore, oligo(p-phenylenevinylene)s with a sulphuric moiety will be synthesized that bind to two opposite gold electrodes. By adding the sulphur lacking analogues a stack will be formed between the two gold electrodes inwhich the sulphur containing oligo(pphenylenevinylene) act as nuclei. The sandwiched architectures have potential applications in (nanosized) field effect transistors (FETs), photovoltaic devices, light-emitting diodes (LEDs) and logic gates. In order to wire these components, designed, interconnecting patterns will be produced with dip-pen lithography. The tip of the AFM will be coated with π-conjugated oligomers and used to write lines of nanometers dimensions. In such a way a unique technology for making future nanodevices is developed.
