Single–molecule conductance measurements: Correlations between chemical design and electronic properties

This thesis is about measurements of the electrical properties of different families of molecules. The research was focused on fundamental questions of charge transport in organic molecules. With this aim, experiments were performed to shed light on the underlying transport mechanisms. For example, an important ingredient of the work concerned the understanding of quantum interference effects in transport. On the other hand, several bio-inspired molecules were tested as electrical components revealing, for example, that with a certain chemical design a single-curcuminoid molecule act as a switch.
