含2,5-二羥基對苯二甲酸根之金屬有機骨架的合成與性質研究
Syntheses and Characterizations of Metal-Organic Frameworks with 2,5-dihydroxyterephthalate
摘要
在本論文中，我們成功以2,5-二羥基對苯二甲酸(H4DOBDC)為有機配位基，利用中溫水熱法合成出10個金屬有機骨架，和微波加熱法合成出4個金屬有機骨架，它們的分子式各自分別為： [Mn2(DOBDC)(DMF)2]•1.5H2O (1)、[Mg2(DOBDC)(H2O)2]•7H2O (2)、[Ln2(DOBDC)(H2DOBDC)(DMF)2] ( Ln = Tb (3), Sm (4), Nd (5) )、[Y2(DOBDC)(H2DOBDC)(DMF)2] (6)、[Y2(DOBDC)(H2DOBDC)(DMF)2] (7)、[CeCl(H2O)3(H2DOBDC)] (8)、[Ce2(H2DOBDC)3(DMF)4]•4H2O (9)、[Ce2(H2O)(H2DOBDC)3]•6H2O (10)、[Mn2(DOBDC)(DMF)2]•3.5H2O (1m)、[Mg2(DOBDC)(H2O)2]•1.5(DMF)0.5(H2O) (2m)、 [Co2(DOBDC)(H2O)2]•1.5(DMF)2(H2O) (3m) 及 [Ni2(DOBDC)(H2O)2]•(DMF)2.5(H2O) (4m)。單晶X-ray繞射分析顯示化合物1和2都是三維骨架結構，為結構的微孔金屬有機骨架。化合物3 ~ 6是三維格子狀的金屬有機骨架，是屬於等結構的化合物。化合物7是與化合物6同分異構物一樣是三維格子狀的金屬有機骨架。化合物8是藉由π-π作用力形成三維結構。化合物9 ~ 10是三維的金屬有機骨架。以上的化合物除了以單晶X-ray繞射儀來鑑定其單晶結構外，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、光激放光光譜和氣體吸附分析來研究所有化合物特性。

Fourteen new metal-organic frameworks, have been synthesized by hydrothermal reactions and microwave synthesis . [Mn2(DOBDC)(DMF)2]•1.5H2O (1), [Mg2(DOBDC)(H2O)2]•7H2O (2), [Ln2(DOBDC)(H2DOBDC)(DMF)2] (Ln = Tb (3), Sm (4), Nd (5) ), [Y2(DOBDC)(H2DOBDC)(DMF)2] (6), [Y2(DOBDC)(H2DOBDC)(DMF)2] (7), [CeCl(H2O)3(H2DOBDC)] (8), [Ce2(H2DOBDC)3(DMF)4]•4H2O (9), [Ce2(H2O)(H2DOBDC)3]•6H2O (10), [Mn2(DOBDC)(DMF)2]•3.5H2O (1m), [Mg2(DOBDC)(H2O)2]•1.5(DMF)0.5(H2O) (2m), [Co2(DOBDC)(H2O)2]•1.5(DMF)2(H2O) (3m) and [Ni2(DOBDC)(H2O)2]•(DMF)2.5(H2O) (4m). Single crystal X-ray diffraction showed that compounds 1 and 2 are isomorphous microporous metal-organic frameworks. The structures of compounds 3 to 7 are all 3D metal-organic frameworsks. The structure of compound 8 consists of π-π interaction that link 2D layer to generate a 3D structure. The structure of compound 9 is a 3D metal-organic frameworsk. These complexes were also characterized by Powder X-ray diffraction, elemental analysis, thermogravimetric analysis, IR spectroscopy, UV-VIS spectra, photoluminescence and gas absorption.
