We present electronic transport measurements through thiolated C(60) molecules in a liquid environment. The molecules were placed within a mechanically controllable break junction using a single anchoring group per molecule. On varying the electrode separation of the C(60)-modified junctions, we observed a peak in the conductance traces. The shape of the curves is strongly influenced by the environment of the junction as shown by measurements in two distinct solvents. In the framework of a simple resonant tunnelling model, we can extract the electronic tunnelling rates governing the transport properties of the junctions.
