A bstract : A simple model of electrical transport through a metal‐aromatic molecule‐metal system that includes charging effects as well as aspects of the electronic structure of the molecule, is presented. The interplay of a large charging energy and an asymmetry of the metal‐molecule coupling can lead to various effects in nonlinear electrical transport. In particular, strong negative differential conductance is observed under certain conditions.
