Stepwise regulation of the molecular conductance was observed in a series of eight biphenyldithiols with fixed torsion angles between the phenyl rings. These compounds were synthesized and their single-molecule conductance was investigated in an STM junction. A cos2 dependence was found between the interplane torsion angle and the single-molecule conductivity (see plot).
