Single-molecule conductance measurements of an antiaromatic compound (1,5-indacene; IND) and an aromatic compound (3,7-benzodithiophene; BZDT), which have nearly identical molecular sizes, revealed that the conductance of IND is approximately ten times higher than that of BZDT. Since their molecular lengths are almost equal, these results demonstrate that the electronic state derived from antiaromaticity is effective in enhancing molecular conductance.
