Single molecule conductance of aromatic, nonaromatic, and partially antiaromatic systems

We describe the syntheses of thiophene, cyclopentadienone and dimethylketalcyclopentadienone derivatives and their single molecule electrical conductivities. The ketone had the lowest conductivity of the three, although it has some antiaromaticity. The carbonyl group is electron attracting and its ionization potential outweighs any conductivity increase that the antiaromaticity effect might bring.
