2,2′‐Diaryl acids are key building blocks for some of the most important and high‐performance polymers such as polyesters and polyamides (imides), as well as structural motifs of MOFs (metal–organic frameworks) and biological compounds. In this study, a direct, regiospecific and practical dimerization of simple aromaticacids to generate 2,2′‐diaryl acids has been discovered, which proceeds through

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).
