抜粋

The long C-C bonds (1.614(2)-1.630(2) Å) in newly prepared title donors 2-6 are cleaved upon two-electron oxidation to afford the bond-dissociated dicationic dyes 2 2+-6 2+, whose electron affinities are stronger than the corresponding biphenyl-2,2′-diyl dications 1 2+ due to the spatial proximity of two xanthenylium units. Not only UV-vis but also fluorescence spectra changed drastically upon electrolysis since only colorless neutral donors are fluorescent.
