Abstract

2-Phenylbenzimidazole-5-sulfonic acid (PBSA) is a water-soluble UV-B absorber used in cosmetic sunscreens. Riboflavin (RF) is a water-soluble vitamin B2. RF is an efficient singlet oxygen photosensitizer. The effects of PBSA on RF-photosensitized singlet oxygen generation have been studied through measurements of transient absorption and time-resolved near-IR phosphorescence in phosphate buffer (pH 7.4). PBSA suppresses the RF-photosensitized singlet oxygen generation. The observed suppression can be ascribed to the quenching of the lowest excited triplet state of RF by PBSA. 2-Phenylbenzimidazole-5-sulfonic acid (PBSA) is a water-soluble UV-B absorber used in cosmetic sunscreens. Riboflavin (RF) is a water-soluble vitamin B2. RF is an efficient singlet oxygen photosensitizer. The effects of PBSA on RF-photosensitized singlet oxygen generation have been studied through measurements of transient absorption and time-resolved near-IR phosphorescence in phosphate buffer (pH 7.4). PBSA suppresses the RF-photosensitized singlet oxygen generation.

水溶性UV-B吸收剂2-苯基苯并咪唑-5-磺酸的新特性:抑制核黄素敏化的单线态氧生成

2-苯基苯并咪唑-5-磺酸(PBSA)是一种用于化妆品防晒霜的水溶性UV-B吸收剂。核黄素是一种水溶性维生素B2。RF是一种高效的单线态氧光敏剂。通过测量磷酸盐缓冲液(pH 7.4)的瞬态吸收和时间分辨近红外磷光，研究了PBSA对rf光敏单线态产氧的影响。PBSA抑制rf光敏单线态氧的生成。所观察到的抑制可以归因于PBSA对RF最低激发态的猝灭。2-苯基苯并咪唑-5-磺酸(PBSA)是一种用于化妆品防晒霜的水溶性UV-B吸收剂。核黄素是一种水溶性维生素B2。RF是一种高效的单线态氧光敏剂。通过测量磷酸盐缓冲液(pH 7.4)的瞬态吸收和时间分辨近红外磷光，研究了PBSA对rf光敏单线态产氧的影响。PBSA抑制rf光敏单线态氧的生成。
