    摘要: 本論文主要以水楊醛、胺類縮合反應合成具希夫式鹼配位基HL1~HL5,再和鐵離子反應,形成一系列的單核鐵(III) 錯合物(1)~(6)。
    具希夫式鹼配位基之鐵(III) 錯合物:
    (1) [Fe(HL1)Cl3]2
    (2) [Fe(HL2)Cl3].CH3CN
    (3) [Fe(HL3)Cl3].CH3CN
    (4) [Fe(HL4)Cl3]2.CH3CN
    (5) [Fe(HL5)Cl2(H2O)] Cl
    (6) [Fe(HL4)Cl2(H2O)] Cl

    L1: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)phenol
    L2: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4-bromophenol
    L3: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4-chlorophenol
    L4: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4,6-dichlorophenol
    L5: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4,6-dibromophenol

    錯合物(1)~(6) 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,並藉由SQUID變溫磁化率的測定,了解錯合物的中心金屬其磁性行為。再加入過氧化氫來了解錯合物是否有反應活性,並探討其酵素動力學。
    A seiries of mononuclear iron(Ⅲ) complexes (1) ~ (6) with Schiff - base ligands HL1~HL5 were synthesized by 2-hydroxybenzaldehyde , amine , and iron(III) chloride.
    Iron(Ⅲ) complexes with Schiff – base ligands were prepared:
    (1) [Fe(HL1)Cl3]2
    (2) [Fe(HL2)Cl3].CH3CN
    (3) [Fe(HL3)Cl3].CH3CN
    (4) [Fe(HL4)Cl3]2.CH3CN
    (5) [Fe(HL5)Cl2(H2O)] Cl
    (6) [Fe(HL4)Cl2(H2O)] Cl
    L1: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)phenol
    L2: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4-bromophenol
    L3: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4-chlorophenol
    L4: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4,6-dichlorophenol
    L5: 2-((E)-(2-(2-(diethylamino)ethylamino)ethylimino)methyl)-4,6-dibromophenol

    The physical properties of complexes (1) ~ (6) were measured by X-ray Single diffraction, UV-Vis spectroscopy, infrared spectra, element analyzer, electronchemical analysises , and electron spin resonance . Magnetic susceptibilities measurements and theoretical calculations were performed to understand magnetic behavior of these complexes. Then added hydrogen peroxide to understand activity and enzyme kinetics of the mononuclear iron(Ⅲ) complexes .
