摘要
采用化学发光法检测并比较了10种二茂铁衍生物清除羟自由基(.OH)活性,用循环伏安法研究了其电化学性质,进而探讨了取代基结构与清除.OH活性间的关系。结果表明,取代基共轭效应、诱导效应和体积都对衍生物清除.OH活性有明显影响。含共轭或吸电子取代基二茂铁衍生物,半波电位(E1/2)较高,清除.OH活性较弱;而含给电子取代基的二茂铁衍生物,E1/2较低,清除.OH活性较强。
The hydroxyl radical（·OH） scavenging activity of ten ferrocene derivates（FcDs） were evaluated by chemiluminescence assay.The electrochemical properties were studied by cyclic voltammetry method.In addition,the relationship between substituent structure and ·OH scavenging activity was discussed.The results indicated that the ·OH scavenging activity was influenced by the conjugative effect,conductive effect and volume of substituents.The FcDs with conjugative or electron-withdrawing substituents,have more positive E1/2 and weaker ·OH scavenging activity,while the FcDs with electron-donating substituents,have more negative E1/2 and stronger ·OH scavenging activity.
