摘要

本論文合成一系列鋅與鎂金屬紫質，並以電化學方法探討金屬紫質的特性。論文中會以光譜滴定先探討一系列金屬紫質與pyridine、imidazole配位基的光譜變化，並計算形成常數來觀察不同錯合物的差異。以循環伏安法觀察紫質與金屬紫質氧化電位差，主要原因在於當紫質大環氧化時，其結構會開始扭曲，加入不同金屬時紫質環扭曲程度則會有差異，因此將觀察此現象並探討其差異性，再滴定pyridine、imidazole配位基觀察錯合物在電化學上的表現。

In this study, a series of zinc and magnesium metal porphyrins are synthesized, and the characteristics of metal porphyrins are discussed by electrochemical methods. In this paper, we will first discuss the spectral changes of a series of metal porphyrins and pyridine and imidazole ligands by spectral titration, and calculate the formation constants to observe the differences of different complexes. The cyclic voltammetry was used to observe the difference in oxidation potential between porphyrins and metal porphyrins. The main reason is that when the porphyrin ring was oxidized, its structure will start to twist. When different metals are added, the degree of distortion of the porphyrin ring will be different. Phenomenon and discuss the difference, then titrate the pyridine and imidazole ligands to observe the electrochemical performance of the complex.
