Abstract

Upon electrochemical oxidation of configurationally stable biphenyl-based electron donors (Rax)-1a and -1b to butane-1,4-diyl dications (M)-2a2+ and -2b2+, drastic changes were induced not only in UV–vis but also in CD spectra. Because of the hydrophilic oligoethylene glycol units on the amino nitrogens, (Rax)-1b and (M)-2b2+ are soluble in water, thus realizing the electrochiroptical behavior not only in organic solvents but also in aqueous media.
