Abstract

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