Charge transport between two molecules

We studied the forces between two single molecules brought into contact, and their connection with charge
transport through the molecular junction using non contact AFM, STM, and DFT
simulations. A carbon monoxide molecule approached to an acetylene molecule (C2H2) feels initially
weak attractive electrostatic forces, partly arising from charge reorganization in the presence of
molecular dipoles. We fou nd that the molecular contact is chemically passive, and protects the electron
tunneling barrier from collapsing, even in the limit of repulsive forces. However, we found a subtle
conductance and force variations at di fferent contacting sites along the C2H2 molecule attributed
to a weak overlap of their respective frontier orbitals.
