    摘要: 本論文合成具兒茶酚及半醌配位基的鐵(Ⅲ)錯合物(1)~(4)，性質及其物性由X-ray單晶繞射儀、UV-Vis光譜、元素分析儀、電化學、電子順磁共振光譜及紅外線光譜方法來分析。
    具半醌及兒茶酚配位基錯合物:
    (1) [Fe(L1)(C6Cl4O2)]2‧OCH3
    (2) [Fe(L2)(C6Cl4O2)Cl2]
    (3) [Fe(L2)(C6Cl4O2)2]
    (4) [Fe(L3)(C6Cl4O2)2]CH3CN‧CH3OH
    L1: 2-((E)-(2-(2-aminoethylamino)ethylimino)methyl)phenol
    L2:(E)-N1-(2-(dimethylamino)ethyl)-N2-((5-methyl-1H-imidazol-4-yl)methylene)
    ethane-1,2-diamine
    L3: N,N-diethyl-2-(2-(pyridin-2-yl)imidazolidin-1-yl)ethanamine

    錯合物(1)~(4)對1,2雙加氧酶在甲醇溶液中的反應活性，由添加入四種不同的兒茶酚陰離子tetrabromocatechol(TBC), tetrachlorocatechol(TCC), catechol(HC),和3,5-di-tert-butylcatechol(3,5-DTBC)與[Fe(L1)Cl2]、[Fe(L2-3)Cl3]反應，根據吸收位置與路易士酸性的關係可發現，路易士酸性越強的錯合物[Fe(L2) 3,5-DTBC]有較佳加氧酶的催化反應性。
    The following complexes(1)~(4) with catecholate and semiquinone ligands
    were synthesized and physical properties of complexes(1)~(4) were measured by
    X-ray Single diffraction, UV-Vis spectroscopy, infrared spectra, element analyzer, and
    Electronchemical analysises.
    Iron(Ⅲ) complexes with catecholate and semiquinone ligands were prepared:
    (1) [Fe(L1)(C6Cl4O2)]2‧OCH3
    (2) [Fe(L2)(C6Cl4O2)Cl2]
    (3) [Fe(L2)(C6Cl4O2)2]
    (4) [Fe(L3)(C6Cl4O2)2]CH3CN‧CH3OH
    L1: 2-((E)-(2-(2-aminoethylamino)ethylimino)methyl)phenol
    L2:(E)-N1-(2-(dimethylamino)ethyl)-N2-((5-methyl-1H-imidazol-4-yl)methylene)
    ethane-1,2-diamine
    L3: N,N-diethyl-2-(2-(pyridin-2-yl)imidazolidin-1-yl)ethanamine

    The methanol solutions of complexes(1)~(4) were titrated with catecholate anions of tetrabromocatechol(TBC), tetrachlorocatechol(TCC), catechol(HC), and 3,5-di-tert-butylcatechol(3,5-DTBC). The results show that the high lewis acidity iron(III) complexes [Fe(L2) 3,5-DTBC] exhibits the higher catechol 1,2-dioxygenase reactivity.
