摘要

Irradiation of a yellowish flavin analogue, riboflavin-2′, 3′, 4′, 5′-tetra-acetate (Fl) in a polymer matrix film as well as in acetonitrile containing benzenethiol derivatives and a base with visible light (λ> 360 nm) results in the decrease in absorbance due to Fl (λ max 442 nm). The color reverts to yellow by irradiation of the samples with ultraviolet light (λ< 360 nm).
