摘要

在本論文中以雙醯胺吡啶配位基[N,N'-di(4-pyridyl)adipoamide (L1)、N,N'-di(3-pyridyl)adipoamide (L2)]，搭配雙羧酸配位基[4,4'-biphenyldicarboxylic acid (H2bpdc)、naphthalene-1,4-dicarboxylic acid (1,4-H2ndc)]，與Cd(II)金屬利用水熱法合成出三個新的金屬-有機骨架，分別為：[Cd(bpdc)(L1)]n (1)．1.5DMF、{[Cd2(1,4-ndc)2(L1)2(H2O)]．H2O．2DMF}n (2)、{[Cd(1,4-ndc)(L2)(H2O)]．2H2O}n (3)。化合物1 - 3利用單晶X-ray繞射儀、粉末X-ray繞射儀、元素分析儀、熱重分析儀、紅外光光譜儀、紫外-可見光光譜儀、氣體吸脫附和螢光光譜儀來研究化合物的特性。
　　單晶X-ray繞射儀鑑定化合物結構，化合物1為一個具有(42,64)(43,67)2拓譜學的兩層交互貫穿之三維網狀結構，化合物2為一個具有(4,62)(42,63,8)(43,65,82)拓譜學的三層交互貫穿之三維網狀結構，化合物3為一個具有(44,62)拓譜學的二維 → 三維之多聚連鎖三維網狀結構。雖然化合物1發生交互貫穿，但是沿著c軸所視，依然具有15.65 × 15.65 Å2的孔洞，其體積佔整個單位晶格體積的47.8 %。化合物2具有三層的交互貫穿而減少了孔洞體積，體積只佔整個單位晶格體積的19.4 %。化合物3的孔洞體積只佔整個單位晶格體積的9.4 %。

This thesis discusses the synthesis and structures of three new metal - organic frameworks (MOFs) containing dipyridyl amide and dicarboxylate ligands. The Cd(II) complexes [Cd(bpdc)(L1)]n (1)．1.5DMF, {[Cd2(1,4-ndc)2(L1)2(H2O)]．H2O．2DMF}n (2) and {[Cd(1,4-ndc)(L2)(H2O)]．2H2O}n (3) have been prepared by the hydrothermal reactions of Cd(II) salts with N,N'-di(4-pyridyl)adipoamide (L1), N,N'-di(3-pyridyl)adipoamide (L2), 4,4'-biphenyldicarboxylic acid (H2bpdc) and naphthalene-1,4-dicarboxylic acid (1,4-H2ndc). All the complexes have characterized by single crystal X-ray diffractometer, powder X-ray diffractometer, elemental analyzer, thermogravimetric analyzer, infrared spectrophotometer, ultraviolet/visible spectrophotometer, gas absorption and fluorescence spectrophotometer.
Single crystal X-ray diffraction showed that complex 1 forms a two-fold interpenetrated 3D framework with a (42,64)(43,67)2 topology, while complex 2 forms a three-fold interpenetrated 3D framework with a (4,62)(42,63,8)(43,65,82) topology and complex 3 displays a 2D → 3D polycatenated framework with a (44,62) topology. Although interpenetration occurs in complex 1, it still exists channels along c axis, with cross sections about 15.65 × 15.65 Å2 and the solvent-accessible volume is 47.8 % of the unit cell volume. However, due to the three-fold interpenetration in 2, the solvent-accessible volume of complex 2 is only 19.4 % of the unit cell volume. The solvent-accessible volume of complex 3 is 9.4 % of the unit cell volume.
