Abstract

Fullerenes are considered anchoring groups for molecular electronics due to a large contact area and their affinity for noble metals. The conductances of fullerene-terminated molecules, however, are found to be even lower than for thiol termination. The effects of weak molecule-metal coupling and symmetry breaking are studied by transport measurements of C₆₀ and functionalized C₆₀. The results demonstrate highy efficient contacts between Au and C₆₀, despite of deposition from solution.
