在本論文中,我們成功以鹼土金屬鎂、鈣、鍶和二價的過渡金屬錳和鋅做為中心金屬,利用中溫水熱合成法以及微波加熱合成法合成出八個不同的新穎有機骨架以及鹼土族在氣體吸脫附上的突破,它們的分子式分別為: [Mg(OBA)(H2O)2] (1) [Ca(OBA)(H2O)] (2) [Sr(OBA)(H2O)] (3) [Mg3(OH)2(SBA)2(EtOH)(H2O)3]•3.5H2O (4) [Ca(SBA)]•(H2O) (5) [Sr(SBA)]•0.5H2O (6) [Mn(SBA)(EtOH)] (7) [Zn3(OH)2(SBA)2]•EtOH (8) 單晶X-ray繞射分析顯示化合物2、3、5、6都是三維骨架結構,結構為微孔的金屬有機骨架;化合物1、4、7、8都是二維結構藉由配位水產生氫鍵作用力形成三維結構,其中化合物4到8也可藉由微波加熱法所合成而得的。 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、氮氣的吸脫附和催化性質來探討所有化合物特性。
Seven new coordination polymers, [Mg(OBA)(H2O)2] (1), [Ca(OBA)(H2O)] (2), [Sr(OBA)(H2O)] (3), [Mg3(OH)2(SBA)2(EtOH)(H2O)3]•3.5H2O (4), [Ca(SBA)]•(H2O) (5), [Sr(SBA)]•0.5H2O (6), [Mn(SBA)(EtOH)] (7), [Zn3(OH)2(SBA)2]•EtOH (8) (DMF= N,N-Dimethylformamide; H2OBA = 4,4'-oxybisbenzoic acid; H2SBA = 4,4'-sulfonyldibenzoic acid), have been synthesized by hydrothermal reactions and microwave synthesis with alkaline-earth elements and carboxylic acid . Single crystal X-ray diffraction showed that compounds 2、3、5、6 are all 3D metal-organic frameworsks. The structure of compound 1、4、7、8 are 2D structure by using the coordinated water to generate the hydrogen bonds and linked to 3D metal-organic frameworks. Moreover, we can use microwave reaction to synthesize compound 4-8. These compounds were also characterized by powder X-ray diffraction, elemental analysis, thermogravimetric analysis, IR spectroscopy, UV-VIS spectra, photoluminescence, gas absorption, and catalytic.
