摘要
光敏氧化效率是由敏化剂分子吸收光量子数及其产生单重态氧的量子产率决定的,这要求敏化剂的吸收光谱同光源的发射光谱很好地匹配。本文报道竹红菌甲素匹配高压钠灯有效地产生单重态氧,高效光敏氧化一系列具有不同反应活性的底物,成为单重态氧化学中一个新的光敏氧化体系。
The kinetics of photosensitized oxygenation of cis, cis-1,5-cyclooctadiene was studied in the presence of different sensitizers. (Rose bengal, Hematoporphyrin, Methylene blue, Hypo-crellin A) matching high pressure sodium lamp. According to the rates of consumption of cis, cis-1, 5-cyclooctadiene, the order of photosensitized oxygenation efficiency is as follows:Hypocrellin A > Methylene blue > Hematoporphyrin > Rose bengal
