Three‐terminal transport is studied in molecular junctions incorporating a single gridlike [Co II 4 L 4 ] (BF 4 ) 8 metallosupramolecular species. The recorded differential conductance as a function of gate and bias voltage (see image) shows reproducible switching behavior in the Coulomb diamonds. BF 4 − counter ions in the vicinity of the molecular junction acting as offset charges are the most likely cause of the observed phenomena.
