含間苯二甲酸-5-磺酸之金屬配位聚合物的合成、結構解析及發光性質研究
Synthesis, Characterizations and Luminescent Properties of Metal Coordination Polymers based on 5-Sulfoisophthalates
摘要
在此篇論文研究中，我們成功地將鹼土金屬中的鎂(Mg)、鈣(Ca)、鍶(Sr)、鋇(Ba)，與有機配位基-間苯二甲酸-5-磺酸鋰(5-Sulfoisophthalic acid monolithium salt)，利用中溫水熱合成法，合成出4個新穎的有機金屬配位聚合物。所合成出的化合物分子式如下： [Mg3(SIP)2(H2O)11] (1) [Ca(MeOH)(HSIP)] (2) [Sr4(HSIP)(SIP)2(H2O)4]•3H2O (3) (H2NMe2)[Ba3(HCO2)(SIP)2] (4) 經由單晶X-ray繞射分析可以得知，化合物1的晶系為Triclinic，結構為三維網狀的金屬有機骨架結構；化合物2的晶系為Triclinic，結構為三維網狀的金屬有機骨架結構；化合物3的晶系為Monoclinic，結構為三維網狀的金屬有機骨架結構；化合物4的晶系為Monoclinic，結構為三維網狀的金屬有機骨架結構。 而這些化合物除了運用單晶X-ray繞射對晶體結構解析外，我們還對其作物理及化學性質上的分析鑑定。利用粉末X-ray繞射、元素分析及紅外線光譜分析，來鑑定其單晶結構的化學式、金屬及有機物的種類和比例，以驗證化合物的種類及純度；利用熱重分析來分析化合物的熱穩定性及熱分解現象；利用紫外光-可見光光譜分析及螢光光譜分析，來鑑定化合物中心配位金屬的環境，以及研究其螢光發光的性質。

Four new coordination polymers have been synthesized by hydrothermal reactions with alkaline-earth metal (Mg、Ca、Sr、Ba) and 5-Sulfoisophthalic acid monolithium salt.Compounds 1 to 4 structure are as follows : [Mg3(SIP)2(H2O)11] (1) [Ca(MeOH)(HSIP)] (2) [Sr4(HSIP)(SIP)2(H2O)4]•3H2O (3) (H2NMe2)[Ba3(HCO2)(SIP)2] (4) (SIP= 5-Sulfoisophthalic acid monolithium salt) The single crystal structure analysis showed these compound. Compounds 1 is a Triclinic and 3D structure. Compounds 2 is a Triclinic and 3D structure. Compounds 3 is a Monoclinic and 3D structure. Compounds 4 is a Monoclinic and 3D structure. The novel compounds were also characterized by powder X-ray diffraction, thermogravimetric analysis, elemental analysis, UV-vis spectra, IR spectroscopy and photoluminescence.
