Excited state intramolecular proton transfer in hydroxyanthraquinones: Toward predicting fading of organic red colorants in art
Compositionally similar organic red colorants in the anthraquinone family, whose photodegradation can cause irreversible color and stability changes, have long been used in works of art. Different organic reds, and their multiple chromophores, suffer degradation disparately. Understanding the detail...
