指導教授 : 曾添文 呂光烈

摘要


本論文分兩部分 (一) 自組裝合成苯咪唑四芽配子與過渡金屬鹽類之配位化合物 以有機配子1,2,4,5-tetrakis(benzoimidazol-1-ylmethyl)-benzene (TBim)各別與過渡金屬中之金屬離子(Cu(II), Co(II), Zn(II))進行自組裝反應,得到化合物1-5。以配子TBim與氯化銅在水熱條件下(120 ℃或140 ℃)反應可分別得{[Cu(TBim)0.5Cl]∙ 0.5 (DMF)}n (1)及{[(CuCl4)(TBimdm)0.5]•(H2O)} (5); 當有機配子(TBim)與鈷及鋅的醋酸鹽類在室溫下反應,可得到{[M(TBim)2(CH3COO)2]•4H2O}n (2; M = Co, 3; M = Zn), 當配子TBim與硝酸鋅在水浴(80 ℃)下反應,可得到{[Zn(TBim)1.5(NO3)](NO3)}n (4)。在第一部分,共可得到四個配位聚合物,及一個有機金屬錯合物。產物1-5經由紅外線共振吸收、元素分析、X光單晶繞射解析等作成份及結構鑑定,在本論文亦會探討其熱穩定性及其發光性質。 (二) 錸金屬離子及有機配子(TBim)作自組裝合成 利用有機配子TBim混合三種不同的醌類的配位基與含錸起始物Re2(CO)10進行水熱自組裝反應,可得到三種錸金屬錯合物6-8。以 1,5-diaminoanthraquinone (Daaq) 為配子時,得到{[Re4(CO)12(TBim)(Daaq)2]∙(toluene)} (6);混以anthrarufin (Atrf) 配子可得到[Re4(CO)12(TBim)(Atrf)] (7);以1,5-diamino-4,8-dihydroxy- anthracene-9,10-dione (Dadh) 配子,得到[Re4(CO)12(TBim)(Dadh)] (8)。錯合物6-8之鑑定及結構解析,及經由紅外線共振吸收、核磁共振氫譜、質譜、元素分析及X光單晶繞射解析,其紫外-可見光吸收與其發光特性亦一併探討。

This thesis is mainly focused on the self-assembly, structure, and properties of metal complexes containing a flexible tetradentate ligand. (1) self-assembled coordination compounds using tetradentate ligand and transition metal salts. Treatment of the organic tetradentate ligand TBim with divalent copper (II) ions under hydrothermal conditions at 120 ℃ and 140 ℃ afforded compounds {[Cu(TBim)0.5Cl]∙0.5(DMF)}n (1) and {[(CuCl4)(TBimdm)0.5]∙(H2O)} (5), respectively. Compounds {[Co(TBim)0.5(CH3COO)2]•H2O}n (2) was prepared by the reaction of TBim with cobalt acetate at room temperature. Compound {[Zn(TBim)1.5(NO3)](NO3)}n (4) was synthesized using TBim and Zinc nitrate at 80 ℃. In the first part, the synthetic procedures used for the preparation of compound 1-5 under different temperatures are discussed. These compounds were analyzed by FT-IR and EA techniques and their structures are confirmed by a single X-ray diffraction analyses. The thermal stabilities, and emission properties of 1-5 were examined and the findings are discussed in detail. (2) Self-assembled rhenium complexes 6-8 Using three types of quinone-containing ligand (1,5-diaminoanthraquinone, anthrarufin, 1,5-diamino-4,8-dihydroxyanthracene-9,10-dione) with a rhenium precursor under solvothermal reaction, it is possible to produce the rhenium complexes ({[Re4(CO)12(TBim)(Daaq)2]∙(toluene)} (6), [Re4(CO)12(TBim)(Atrf)] (7), [Re4(CO)12(TBim)(Dadh)] (8)). These compounds were characterized by FT-IR, EA and their structures were confirmed by a single-crystal X-ray diffraction analysis. The UV-vis absorption, and emission properties of compounds 6-8 were also examined and the results are discussed in detail.
