在本論文的第三章中,我們成功以鋰金屬(Li)做為中心金屬,利用中溫水熱合成法合成出四個新穎的鋰金屬配位聚合物,它們的分子式分別為: [Li2(MA)] (WC-1) [Li4(H2O)2(EDTA)] (WC-2) [Li4(H2O)4(BTCA)] (WC-3) (H2NMe2)2[Li2(H2O)2(BTCA)] (WC-4) 單晶X-ray繞射分析顯示化合物WC-1和WC-2都是三維骨架結構;化合物WC-3是二維層狀結構;化合物WC-4則是一維鏈狀結構。以上的化合物除了以單晶X-ray繞射儀來鑑定其分子結構外,還利用其它的分析工具如粉末X-ray繞射分析、元素分析、熱重分析、紅外光光譜、循環伏安法、充放電測試等,來探討化合物特性。 在第四章中,我們利用微波輔助合成法成功的製備出文獻中利用水熱法合成出來五個鋁金屬有機骨架的MOF孔洞材料,分別為: [Al(OH)(NDC)] (DUT-4) [Al(OH)(BPDC)] (DUT-5) [Al(OH)(BDC)] (MIL-53) [Al(OH)(aBDC)] (MIL-53N) [Al3O(H2O)2(OH)(BTC)2] (MIL-100) 以上化合物,我們利用BET孔洞吸脫附儀測試材料對於N2的氣體吸附性質、孔洞大小及比表面積,並利用SEM觀察材料型態與尺寸,最後經由Biginelli reaction和sulfoxidation of aryl sulfides來測試材料的催化活性。
Four new lithium coordination polymers, [Li2(MA)] (WC-1), [Li4(H2O)2(EDTA)] (WC-2), [Li4(H2O)4(BTCA)] (WC-3) and, (H2NMe2)2[Li2(H2O)2(BTCA)] (WC-4), (H2MA = malonic acid, EDTA = ethylenediaminetetraacetic acid, BTCA = 1,2,3,4-butane tetracarboxylic acid, H2NMe2 = N,N’-dimethylformamide,) are synthesized from lithium ions and aliphatic carboxylic acids under solvothermal reactions. The single crystal X-ray diffraction showed that compound WC-1 and WC-2 both are 3D frameworks structure, compound WC-3 has 2D sheets, and compound WC-4 has 1D chains. These complexes were also characterized by powder X-ray diffraction, elemental analysis, thermogravimetric analysis, Fourier transform infrared spectroscopy, cyclic voltammetry and charge-discharge test. A series of aluminum metal-organic frameworks (MOF), Al(OH)(NDC) (DUT-4), Al(OH)(BPDC) (DUT-5), Al(OH)(BDC) (MIL-53), Al(OH)(aBDC) (MIL-53N), and Al3O(H2O)2(OH)(BTC)2 (MIL-100) which constructed by 2,6-naphthalenedicarboxylic acid (H2NDC), biphenyl-4,4'-dicarboxylic acid (H2BPDC), terephthalic acid (H2BDC), 2-aminoterephthalic acid (H2aBDC), trimethyl 1,3,5-benzenetricarboxylate (Me3BTC) and aluminum ions under facile microwave-assisted reactions. All MOFs have been characterized by BET, SEM and catalytic properties by Biginelli reaction and sulfoxidation of aryl sulfides.
