%X We use scanning tunneling microscopy to establish controlled contacts to single molecules of endohedrally doped Ce-2@C-80 fullerenes with C-60 as a reference. The stability of the experimental setup allows for the determination of the conductance of Ce-2@C-80 relative to the conductance of C-60. The endohedral doping reduces the conductance of Ce-2@C-80 by a factor of about five with respect to C-60. Ab initio calculations show that the reason for this reduced conductance is the absence of electron orbitals delocalized over the cage of Ce-2@C-80 in the energy window of the conductance measurement.
