Photoinduced Chemiluminescence in 9-Anthrone Solution

Interaction of a photoirradiated anthrone solution in dioxane with an aqueous base solution (0.1 mol l⁻¹ NaHCO₃) was accompanied by chemiluminescence. The product possessing chemiluminescent activity was accumulated in the solution within three hours of continuous UV irradiation (λ_max ∼ 365 nm). It was retained in the solution within several days after irradiation. This product was supposed to be dianthrol. The maximum of the chemiluminescence spectrum is at 540–555 nm, which shows that the chemiluminescence emitter is the anthrol anion.__________Translated from Khimiya Vysokikh Energii, Vol. 39, No. 4, 2005, pp. 255–258.Original Russian Text Copyright © 2005 by Tsaplev, Vasil’ev.
