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).

bridges. The key intermediates 14 and 15 were transformed into the corresponding cycloheptadienones 16 and 17, which were reduced to the desired propyl-bridged biphenyls 3b and 3c. The butyl-bridged derivatives 4b and 4c were obtained from 14 and 15 by an allylation reaction followed by ring-closing metathesis (RCM) and hydrogenation. The pentyl chain in precursor 24 was obtained by two aldol C-C bond-forming
