銪金屬配位聚合物的水熱合成、結構鑑定與性質研究
Hydrothermal Synthesis, Structural Characterization, and Properties of Europium Coordination Polymers.
摘要
在本論文中，我們成功以鑭系金屬銪(Eu)做為中心金屬，利用中溫水熱合成法以及微波加熱合成法合成出十三個不同的新穎有機骨架，它們的分子式分別為： [Eu2(DOBDC)(H2DHBDC)(DMF)2](1) [Eu2Cl(HDOBDC)(DOBDC)(H2O)2]•4H2O(2) [Eu2(DOBDC)3]•2H2O(3) [Eu2(H2DOBDC)3(DMF)4]•4H2O](4) [Eu(oBDC)3(H2O)](5) [Eu(mBDC)3(H2O)2](6) [Eu(oCDC)3(H2O)2](7) [Eu2 (BHC)(H2O)6](8) [Eu(NIP)2(H2O)2]•2H2O(9) [Eu2(NIP)3(H2O)2]•3H2O (10) [Eu2(PDA)3(H2O)]•2H2O(11) [Eu3(BDC)4.5(DMF)2(H2O)](12) [Eu(HCO2)(NDC)] (13) 單晶X-ray繞射分析顯示化合物1到4、8、11到13都是三維骨架結構，結構為微孔的金屬有機骨架；化合物5、9、10都是藉由配位基的π-π作用力形成三維結構，其中化合物4是由微波加熱法所合成而得的；另外，化合物2則可以利用微波加熱法合成出與水熱合成法相同結構的晶體。 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、紫外-可見光吸收光譜、光激放光光譜、氮氣的吸脫附、磁性分析和催化性質來探討所有化合物特性。

Thirteen new coordination polymers, [Eu2(DOBDC)(H2DHBDC)(DMF)2](1) , [Eu2Cl(HDOBDC)(DOBDC)(H2O)2]•4H2O(2), [Eu2(DOBDC)3]•2H2O(3), [Eu2(H2DOBDC)3(DMF)4]•4H2O](4), [Eu(oBDC)3(H2O)](5), [Eu(mBDC)3(H2O)2](6), [Eu(oCDC)3(H2O)2](7), [Eu2(BHC)(H2O)6](8), [Eu(NIP)2(H2O)2]•2H2O (9), [Eu2(NIP)3(H2O)2]•3H2O (10), [Eu2(PDA)3(H2O)]•2H2O (11), [Eu3(BDC)4.5(DMF)2(H2O)] (12), [Eu(HCO2)(NDC)] (13) (DMF= N,N-Dimethylformamide; H4DOBDC=2,5-Dihydroxy-terephthalic acid; oBDC= Phthalic acid；mBDC= Isophthalic acid; oCDC= cis-1,2-cyclohexane-dicarboxylic acid; BHC= Benzenehexacarboxylic acid; NIP = Bis(2-hydroxyethyl) terephthalate ; PDA=1,4-Phenylenediactic acid; BDC=1,4-benzene dicarboxylate anion; NDC=2,6-Naphthalenedicarboxylic acid), have been synthesized by hydrothermal reactions and microwave synthesis with rare-earth elements and carboxylic acid . Single crystal X-ray diffraction showed that compounds 1 to 4、8、11 to 13 are all 3D metal-organic frameworsks. The structure of compound 5、9、10 consists of π-π interaction that link 2D layer to generate a 3D structure. On the other hand, compound 2 can use microwave reaction synthesis the same structure. These complexes were also characterized by Powder X-ray diffraction, elemental analysis, thermogravimetric analysis, IR spectroscopy, UV-VIS spectra, photoluminescence, gas absorption, magnetic and catalytic.
