Back electron transfer of the redox intermediates generated by irradiation of the supramolecular complex 1 is 10 4 times slower than in the free triad. In 1 , in which a dialkoxybenzene derivative is positioned between two bipyridinium arms of the triad, the distance between the redox centers is greater than in the free Ru II complex.
