cations of dihydropteridine and dihydroflavin are formed in the photoreduction of pteridine and flavin analogues, respectively, by benzyl alcohol derivatives in the presence of perchloric acid in acetonitrile via photoinduced electron transfer from benzyl alcohol derivatives to the triplet excited states of protonated pteridine and flavin analogues. Their ESR spectra and the stabilities are compared.
