“…The first of these series includes MV oxidized norbornadiene [C 7 H 8 ] + ( I ) and its polycyclic derivatives [C 12 H 12 ] + ( II ), [C 17 H 16 ] + ( III ), [C 27 H 24 ] + ( IV ) and [C 32 H 28 ] + ( V ), each containing two terminal CC chromophores acting as redox centers and the bridges of increasing length mediating the charge transfer between these chromophores. 19 Note that in the above calculations we have just used the values of the parameters obtained in ref. 19 for one of the compounds of this series, namely, for II .…”
