Abstract Using a scanning tunneling microscope-based break-junction technique, we assessed the conductance of single-molecule junctions formed with three distinct molecular wires, each featuring cyclic five-membered ring: furan, cyclopentanone or cyclopentadiene. We found that these wires correlates their aromaticity; non-aromatic cyclopentadienone derivative exhibits highest conductance, while most aromatic furan in this series displays lowest conductance. Additionally, lower HOMO-LUMO gap anti-aromatic compounds may also contribute to effect. This discovery aids understanding influence structure on conductive properties and provides crucial insights for design optimization electronic devices.
