    • The C-O bond heterolysis of both pyran rings synergistically to yield highly conjugated bis-opened forms does not appear to occur in 3-5 as reflected from the absorption spectra of the intermediates, which closely resemble those of the intermediates of the model analogs 6 and 7. In general, considerable shifts in the absorption maxima have been observed for bis-opened forms relative to those of the mono-opened forms, see:

    • It is intriguing that the decay of the o-quinonoid intermediate of 3 follows an almost monoexponential function as compared to the behaviour observed for those of 4 and 5. We believe that the electronic factors intrinsic to the aryl rings are transmitted differently in 6- and 7-arylchromenes
