摘　　要：卟啉是一种具有良好光敏性的特殊大环共轭芳香化合物。文章利用活性自由基聚合的方法,以不对称羟基金属卟啉为原料,合成出具有温度响应性聚合物修饰的金属卟啉光敏剂,并通过核磁谱图分析证实了目标产物的结构。又以其作为光催化降解光敏剂,降解有机污染物亚甲基橙。考察不同光降解反应条件下,卟啉聚合物在氧化剂H_2O_2存在下,可见光照射下降解率最佳。同时也考察了不同温度、分子量、pH对光催化降解的影响。Porphyrin is a kind of special conjugated aromatic compounds with good photosensitive properties. Methods using active free radical polymerization, with asymmetric hydroxyl metal porphyrin as raw material, synthesized with temperature responsive polymer modified metal porphyrin photosensitizer. The structure of the target product was confirmed by the analysis of the NMR spectra. And methylene orange of organic pollutants was degradated with polymer as photocatalytic. Degradation rate of methylene blue were best using porphyrin polymers in the presence of oxidizing agent H2O2 under visible light irradiation. It also examines the effects of different temperature, molecular weight, PH on Photocatalytic degradation.
