光譜電化學在金屬紫質的應用

Spectroelectrochemistry of Metalloporphyrins

摘要


自1970年代桑名教授(Theodore Kuwana)利用薄層電極研究細胞色素氧化酵素(cytochrome oxidase)的電子轉移,許多科學家辨利用光譜電化學方法,言就金屬紫質的氧化還原性質。利用電分析儀控制電位,配合是當的光譜方法分析,可以了解金屬紫質在得到或失去電子後的狀態。這對於利用金屬紫質模擬生化系統,如細胞色素P-450的氧原子轉移反應等是非常重要的。下面就幾種金屬紫質的光譜電化學研究做一簡要概述。

並列摘要


In the seventies, Professor Theodore Kuwana used thin-layer spectroe lectrochemical technique to study the electron transfer of cytochrome oxidases. Since then, many scientists take the advantage to work on metalloporphyrin redox reactions . By applying suitable potential to metalloporphyrin systems and by taking the spectra at the same time, either the oxidized or reduced species can be identified. This characterization is essential for the mimicking the biosystems by metalloporphyrins. Some examples have been selected to illustrate the application of spectroe lectrochemistry on metalloporphyrins.
