bipy = 2,2‘-bipyridine]. Electronic communication between the two 2,2‘-bipyridylboronium substituents of each compound was observed, suggesting the reduced radical species to be partially delocalized redox intermediates. The degree of electronic interaction is largely independent from the degree of conformational flexibility of the individual molecule. While charge-transfer processes from the electron-rich
