本論文分別利用不同有機配子與鑭系金屬離子、過渡金屬離子進行反應,分為兩類: (一) 利用2,4,6-tri(2-pyridyl)-1,3,5-triazine (Tpt) 與金屬離子鉺、釤、釓、銀進行水熱法或室溫法自組裝合成。與硝酸鉺反應得到配位化合物[Er2(Tpt)2(C2O4)]•(H2O) (1);與硝酸釤反應得到配位化合物[Sm(Tpt)(H2O)](H2O)2 (2); 與硝酸釓反應得到化合物[Gd(Tpt)(H2O)]•(H2O)2 (3); 與硝酸銀反應意外得到一維配位聚合物[Ag(Tpt)]n (4)。 (二) 利用1,2,4,5-benzenetetracarboxylic acid (BETC), 5-5’-bipyrimidine (bpy)有機配子,與硝酸鋁進行室溫法自組裝合成,在potassium hydroxide調控pH值之條件下,反應得到含鉀離子的三維配位聚合物[K(bpy)(BETC)]n (5)。 本論文共合成五個新型金屬-有機配位化合物,其結構除了以IR, EA, UV-visible等分析外,進一步再以單晶及粉末X射線繞射解析鑑定,並利用TGA測定其熱安定性。
Treatment of MNO3•nH2O (M = Er, Sm, or Gd) with 2,4,6-tri(2-pyridyl)-1,3,5-triazine (Tpt) in acetonitrile under hydrothermal condition led to the formation of metal complexs [Er2(Tpt)2(C2O4)]•(H2O) (1), [Sm(Tpt)(H2O)](H2O)2 (2), and [Gd(Tpt)(H2O)]•(H2O)2 (3). The reaction of Tpt with AgNO3 at ambient temperature yielded a 1-D metal-organic polymer [Ag(Tpt)]n (4). A mixture of 1,2,4,5-benzenetetracarboxylic acid or carboxylate (BETC), 5,5’-bipyrimidine (bpy), and potassium hydroxide in the presence of Al(NO3)3 at room temperature produced a 3-D coordination polymer [K2(bpy)(BETC)]n (5). Products 1-5 were characterized by elemental analysis, IR- and UV-vis spectroscopy and by thermal analysis. The molecular structures of the discrete compounds 1-3, and coordination polymers 4-5 were further confirmed by single- crystal X-ray diffraction analysis.
