    Abstract: 本論文主要研究以取代水楊醛,1.3-diamino-2-propanol進行Schiff-base縮和反應合成三種配位基L1~L4 ,再分別與過氯酸銅反應,最後加入不同的架橋基,合成二個雙架橋雙核銅及二個四核銅之錯合物。內容分成三部分,第一部份是探討不同架橋基對於銅錯合物磁性行為的影響;第二部分是利用理論計算探討錯合物的電子密度;第三部分是討論兒茶酚酶反應活性。

    四個錯合物complexes (1)~(4)分別為:
    (1)〔Cu2(L1)(C3H3N2)〕
    (2)〔Cu2(L1)2(C5H6O4)〕
    (3)〔Cu2(L2)2(C10H8O4)〕
    (4)〔Cu2(L3)(C6H5N4O)〕
    L1:【 1,3-bis(3-tert-butylsalicylideneamino)propan-2- ol】;
    L2:【1,3-bis(salicylideneamino)propan-2-ol】;
    L3:【1,3-bis(3,5-di-tert-butylsalicylideneamino)propan-2- ol】

    以上錯合物進行單晶結構的解析、元素分析、紅外線光譜、SQUID變溫磁化率( 2 ~ 300k )等測定。同時論文中更加入理論計算,來了解銅與銅間配位立體結構與磁性行為之關連性。最後進行此系列金屬錯合物之兒茶酚酶反應活性及動力學之研究。
    A series of dinuclear and teranuclear copper(Ⅱ) complexes (1)~(4) containing Schiff-base, derived from salicylaldehyde, 3-tert-butyl-2-hydroxybenzaldehyde , 3,5-di-tert-butyl-2-hydroxybenzaldehyde, and 1,3-diamino-2-propanol are reported. These dinuclear and teranuclear complexes are bridged by pyrazole,6-methoxypurine,
    dimethylmalonic acid, 1,4-phenylenediacetic acid.
    These complexes are:
    (1)〔Cu2(L1)(C3H3N2)〕
    (2)〔Cu2(L1)2(C5H6O4)〕
    (3)〔Cu2(L2)2(C10H8O4)〕
    (4)〔Cu2(L3)(C6H5N4O)〕
    L1:【 1,3-bis(3-tert-butylsalicylideneamino)propan-2- ol】;
    L2:【1,3-bis(salicylideneamino)propan-2- ol】;
    L3:【1,3-bis(3,5-di-tert-butylsalicylideneamino)propan-2- ol】

    The complexes have been characterized by single crystal X-ray, elemental analysis, IR spectra,Variable-temperature ( 2 ~ 300K ) magnetic susceptibility,Theoretical studies (DFT) have been performed to understand magnetic behavior of these complexes. The reactive activities of copper(Ⅱ) complexes for catecholase-like also are investigated.
