Abstract

Polymer-dispersed perylene di-imide dye photodegradation is investigated by monitoring the fluorescence intensity as a function of 532   nm laser pulses. Anaerobically irradiated polymer–dye films exhibited an accelerated decrease in fluorescence intensity, which was partially recovered upon exposure to oxygen. Decelerated photodegradation rates were observed for perylene di-imide ethanol solutions upon the addition of a singlet oxygen quenching antioxidant. These observations suggest reversible photoreduction and type II photo-oxidation as important photodegradation mechanisms. Type II photo-oxidation for perylene red 532   nm irradiation is supported by a singlet oxygen quantum yield of 0.09 ± 0.03 , determined via detection of time-resolved O 2 ( a 1 Δ g X 3 g     ) infrared phosphorescence.
