摘要

本研究利用有機混合配位基與二價鎳及二價鈷離子以中溫水熱法、溶劑熱法以及微波輔助合成法反應合成出九個配位聚合物，其化學式分別為
[Ni2(MAL)2(bpy)(H2O)2](1)、
[Ni(NB)2(bpy)2](2)、
[Ni2(PDA)2(bpp)2(H2O)3]•H2O(3)、
[Ni(mBDC)(bpp)](4)、
[Co(NB)2(bpy)2](5)、
[Co2(NB)4(bpp)2(H2O)]•H2O(6)、
[Co(COD)(bpp)](7)、
[Ni2(COD)2(bpp)2(H2O)4](8)和
[Ni3(BTC)2(H2O)12](9)。其中的有機配位基： bpy 是4,4’-雙吡啶、bpp 是4,4’-三甲基雙吡啶、MAL是丙二酸、NB是3-硝基苯甲酸陰離子、PDA是1,4-對苯二乙酸陰離子、mBDC是1,3-苯二甲酸陰離子、BTC是1,3,5-苯三甲酸陰離子、COD是1,4-二甲酸環己烷陰離子。單晶結構分析顯示化合物1和7是三維骨架結構；化合物2、3、5、6和8是二維層狀結構；化合物4和9是一維無限延伸的鏈狀結構。以上九個化合物除了以單晶X光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光繞射分析、元素分析、熱重分析、磁性測量、紅外光共振光譜、紫外-可見光吸收光譜和螢光光譜來研究化合物的物理性質與化學性質。這些化合物的光致發光在大約400 nm左右。由磁化率數據得到在低溫下化合物1具有鐵磁性，2、3、4、5、6、7和8則具有反鐵磁性；化合物5在常溫下具有鐵磁性。

The hydrothermal, solvothermal, and microwave assisted reactions of organic mixed-ligands with Ni(II) or Co(II) ions provided nine metal coordination polymers, [Ni2(MAL)2(bpy)(H2O)2](1), [Ni(NB)2(bpy)2](2), [Ni2(PDA)2(bpp)2(H2O)3]•H2O(3), [Ni(mBDC)(bpp)](4), [Co(NB)2(bpy)2](5), [Co2(NB)4(bpp)2(H2O)]•H2O(6), [Co(COD)(bpp)](7), [Ni2(COD)2(bpp)2(H2O)4] (8), and [Ni3(BTC)2(H2O)12] (9) (MAL = malonate anion; bpy = 4,4'-bipyridine; NB = 3-nitrobenzoate anion; PDA = 1.4-phenylenediacetate anion; bpp = 4,4’-trimethylene dipyridine; mBDC = 1,3-benzene dicarboxylate anion; BTC = 1,3,5-benzene tricarboxylate anion; COD = 1,4-cyclohexane dicarboxylate anion). The crystal structure analysis showed that compound 1 and 7 with infinite 3D framework, compound 2, 3, 5, 6 and 8 with 2D sheets, and 4, and 9 with 1D chain. The further examinations of IR, TGA, PXRD, UV-vis, photoluminescent spectra, and magnetic susceptibility were also measured. Compounds 1-8 exhibit blue-violet photoluminescence around 400 nm in the solid state. The variable temperature magnetic susceptibility data showed that at low temperature compound 1 with the ferromagnetism, while 2, 3, 4, 5, 6, 7 and 8 with the anti-ferromagnetism, besides at room temperature the compound 5 with the ferromagnetism.
