Sulfur-substituted nucleobases (i.e., thiobases) are a prospective class of compounds for clinical and cosmetic topical phototherapies. Recent investigations of several thiobases have revealed the ultrafast and efficient population of reactive triplet states upon ultraviolet-A (UVA) irradiation and the subsequent generation
