Relaxation study of excited aqueous hydroxypyrenes
The relaxation mechanism of electronically excited 8-hydroxypyrene-1,3,6-trisulfonic acid (HPT) and 6,8-dihydroxypyrene-1,3-disulfonic acid (DPD) has been studied using flash perturbation method in aqueous solution. The recombination rate constants kr of the solvated electron (ejected from the excited state of the dissociated acids) have been determined. No electron ejection takes place in aqueous 8-aminopyrene-1,3,6-trisulfonic acid (APT).
