Abstract

While present-day electronic appliances already encompass organic materials (e.g. liquid crystals or TFT screens), there remains an enormous potential for single molecules and their assemblies as functional components in future electronic devices. Their minute size and large structural variety not only make molecules promising modular building blocks for nanoscale electronic systems, but also comprise an enormous application field for the development of basic science and technology. Driven by both the huge application potential and the new fascinating scientific challenges, chemists and physicists are gathering here to pursue the development of a novel molecule-based nanoelectronic.

This is how the field of single-molecule electronics may be introduced in a typical proposal today. The truth is, however, that the field is currently accumulating results with each group using different molecules in a different setup with different conclusions. Though many papers have been focused on “the conductance” of a particular molecule, it is even not clear whether such a question is properly defined – i.e. defined in a scientific way so that reproducible results can be obtained: results that can be gathered by other researchers at another place and time and are then “the same”. Today, the field is flooded with single results of all kind.  

Fortunately, it appears to us that this is changing now. For the simplest conceivable molecules, reproducible results emerge at different labs. However, reproducible single molecule junctions is, but the first step. We must agree on a set of building blocks with which a “universal” electronics can be built (assembled). From this latter aspect, I think we are still MILES away.
