Abstract: The study of photogenerated reactive oxygen species (ROS) and their downstream dark reactions. Here we use phase separation and interfacial chemistry in an attempt to deconvolute these processes and study specific primary light-dependent and secondary dark reaction mechanisms. Studying the downstream reactions of primarily formed peroxides has yielded valuable insight into multistage oxidative events, and allows ROS to be rationally manipulated and their reactivity tuned. We also relate our findings the biological uses of ROS, toxic free radicals in air pollution, and in designing plastics and materials for rapid photodegradation in landfills and oceans.
