Photodecomposition of Optical Bleaching Agents in the Presence of Arenes and Arenesulfonic Acids

摘要

Addition of arenes and arenesulfonic acids to optical bleaching agents in the liquid system 2-propanol-water or in a polyvinyl alcohol matrix affects the rate of their photodecomposition via T-T transfer of the electronic excitation energy.The relative arrangement of the triplet levels of the luminophore and added compound is responsible for acceleration or deceleration of the process.
