Notes:
The acceleration of the photolysis of several anthraquinone derivatives by admixture of various substances, notably of carbonyl compounds ans lead(IV) salts has been studied in a variety of solvents. The sensitization of the photolysis results from the production of radicals either directly from the irradiated lead salts or from the solvent upon hydrogen atom abstraction by the excited carbonyl compounds, probably in the triplet state. The reaction of these radicals with the dye results in the formation of several derivatives of its leuco form, whose absorption in the visible and ultraviolet closely resemble that of the unsubstituted leuco form. These reactions are observed in very dilute solutions, in which intermolecular energy transfer is not expected to occur.
