“…Quinones are known to be rapidly reduced by superoxide radicals to form semiquinone radicals via electron transfer and hydrogen atom abstraction [38]. Similar reactions have been reported for anthraquinone dyes [39]. If superoxide generation by the irradiated MC is involved in the production of the peroxy radicals and hydroperoxides in the polymer that give rise to PICL emission, then the presence of anthraquinone dyes may limit this process and reduce the PICL intensity.…”

Photolysis of an azo, a quinophthalone, and several anthraquinone smoke dyes was studied on soil surfaces. Initially, rapid photodegradation of each dye occurred, followed by a period of much slower rate of loss, indicating that the remaining fraction of the dye was photochemicaily protected. The average mean depths of photolysis ranged from 0.33 to 0.68 mm for outdoor studies and from 0.42 to 0.73 mm for lab studies. The magnitude of the mean depths of photolysis suggests that photo‐degradation of the dyes occurs through indirect photochemical processes. Photolysis products for only two of the dyes could be identified. Photolysis of Disperse Red 9 resulted in the formation of 1‐aminoanthraquinone, whereas Solvent Yellow 33 photo‐degraded to give 2‐carboxyquinoline and phthalic anhydride. Reaction mechanisms involving sensitized photo‐oxidation by singlet oxygen are consistent with the formation of these reaction products.
