Ions derived from dianthrylethane species. How the mode of linking affects the intramolecular electron transfer

Article abstract of DOI:10.1021/ja00004a009

Chemical and electrochemical reduction of dianthryl compounds affords mono-, di-, tri-, and tetraanions via successive electron-transfer processes. The diamagnetic or paramagnetic ions are characterized by NMR and ESR spectroscopy, respectively, by cyclic voltammetry, and by quenching reactions. The title dianthryl systems have in common that two anthracene units are linked by ethane bridges in a sterically variable fashion. It appears that the mode of linking drastically affects the rate of intramolecular electron-transfer processes in radical monoanions as well as the charge-storage behavior.
