摘要:	本研究採用有機配子 2,5-(thiophenediyl)dibenzoic acid (H 2 TDB)分別與不同的金屬鹽類反應，製備七個有機金屬配位聚合物，以單晶 X-ray 繞射解析其構造，並研究其結構及螢光性質。本論文分為三個部分，第一部份化合物 [Zn(TDB)(H2O)]n (1)、[Co(TDB)(H2O)2]n (2)、[Cd2(TDB)2(H2O)3]n (3)，是以過渡金屬離子與 H2TDB 反應形成不同的配位聚合物，透過單晶繞射分析的結果顯示出化合物 1 及化合物 3 具有 2D 結構，而化合物 2 則是3D 結構。其中由於化合物 1 及化合物 3 的中心金屬具有 d 10 的電子軌域，再加上有機配體本身的螢光特性，因此化合物 1 及 3 具有顯著的發光性質；除此之外，化合物 3 為非中心對稱的結構，因此也對其圓二色性 (CD) 進行探討，並透過二次倍頻 (SHG) 證實化合物 3 具有非線性光學的性質。化合物 [Ln2(TDB)3(NMP)(H2O)]n (Ln = Tb (4)、Eu (5)與 Gd (6))是以鑭系金屬離子與 H2TDB 反應製備了相同結構、不同中心金屬的 2D 配位聚合物，且具有顯著的螢光特性。化合物 [Mg(TDB)(H2O)2]n (7) 則是以鹼土金屬鎂鹽與 H2TDB 反應，形成結構類似化合物 2 的 3D 的配位聚合物，並同樣的對其進行螢光性質的探討。;In this thesis, a series of supramolecular compounds and coordination polymers were synthesized by the reaction of the organic ligand, 2,5-(thiophenediyl)dibenzoic acid (H2TDB), and different types of metal ions via self-assembly processes. Their structures and properties were studied and discussed. Compound [Zn(TDB)(H 2 O)] n (1), [Co(TDB)(H2O)2]n (2), and [Cd2(TDB)2(H2O)3]n (3), were produced by the reaction of zinc salts, cobalt salts or cadmium salts, respectively, with the H2TDB ligand. The structures of the compounds were characterized by single-crystal X-ray diffraction analyses. Compounds 1 and 3 adopt 2D structures and compound 2 forms a 3D structure. Because of the d 10 electron orbital of metal centers (Zn in 1 and Cd in 3) and the luminescence property of H2TDB, the luminescence properties of these compounds were investigated. In addition, the space group of compound 2 showed that it has a non-centrosymmetric structure, so its circular dichroism and nonlinear optical property were examined. Compounds [Ln2(TDB)3(NMP)(H2O)]n (Ln = Tb (4)、Eu (5) and Gd (6), NMP = 1-Methyl-2-pyrrolidone) were synthesized by the reaction of terbium salts, europium salts, orgadolinium salts with the H 2 TDB ligand. A series of isostructures with 2D layers were produced and their luminescence properties were also studied and discussed. Compound [Mg(TDB)(H2O)2]n (7) was synthesized by treating a magnesium salt with the H2TDB ligand. The single-crystal X-ray diffraction analysis showed that compound 7 adopts a 2D structure. Its luminescence property was also examined through emission studies.
