【摘要】：具有新颖结构的芳香竣酸类配合物在药物传递、分子识别、气体吸附与分离等领域的潜在应用价值引起了越来越多人的关注。本论文基于三联苯-3,3",5,5"-四甲酸配体与过渡金属和稀土金属合成出了 17种结构新颖的配合物,对其进行了 X-射线单晶衍:射分析、红外、热重和粉末衍射测试,对配合物1、8、12和14进行了荧光性能分析,对配合物2、3、5、6、7、9和10进行磁性研究。配合物1对对硝基苯胺具有良好的检测性配合物8则对对硝基甲苯选择性更强,配合物14对硝基苯胺有良好的检测性。配合物1～17的分子式如下:[Cd(tptc)_(0.5)(4,4,-bibp)]n(1){[Co(tptc)_(0.5)(4,4’-bibp)]-(H_2O)·(Cyc)}n(2){[Ni(tptc)_(0.5)(4,4'-bibp)]·(H_2O)·(Cyc)}n(3){[Ni(tptc)_(0.5)(4,4,-bibp)(H_2O)2]·6(H_2O)}n(4){[Co(tptc)_(0.5)(4,4,-bibp)]·(H_2O)·(4,4,-bibp)0.5}n(5){[Co(tptc)_(0.5)(1,4-bib)]-(H_2O)·(DMF)}n(6){[Mn(tptc)_(0.5)(1,4-bbimb)]-2(H_2O)}n(7)[Zn(tptc)_(0.5)(1,2-bimb)]n(8){[Cu_2(tptc)(1,2-bimb)2]-4.5(H_2O)}n(9)[Co_2(tptc)(1,2-bimb)(H_2O)2]n(10){[Ni(tptc)_(0.5)(1,2-bimb)](H_2O)]-(H_2O)}n(11){[Zn2(tptc)(1,4-bimb)2]·(H_2O)}n(12)[Cu(tptc)_(0.5)(1,3-bimb)]n(13){[Zn3(Htptc)2(phen)2]-1.5H_2O}n(14){[Eu2(tptc)1.5(H_2O)4]-2(H_2O)-2(1,4-DOX)}n(15){[Ce(tptc)(H_2O)4]-0.5(H_2O)·0.5(1,4-DOX)}n(16){[Pr(tptc)(H_2O)5]·(H_2O)-0.5(1,4-DOX)}n(17)单晶结构分析表明配合物4、9、10、11、13、14、和16为2D双层结构,配合物4和11为双链形成的2D结构,配合物11通过氢键作用将结构扩展成3D网络结构;配合物9、10、13和14中辅配体只对由主配体和金属离子形成的二维面进行修饰,9具有一个的sq1拓扑结构而13属于kgm拓扑结构,10中含有大量氢键,氢键使配合物更稳定,配合物16则通过氢键作用扩展成3D网络结构,配合物14通过π-π作用扩展成3D网络结构。配合物1、2、3、5、6、7、8、12和15都是3D结构,其中配合物1、2、3、5、6和7具有相同的三维拓补结构,配合物8和12都是一个4,4-连接的三维结构,配合物15为4,4,12-连接的3D网络结构。配合物17为1D结构,通过氢键作用扩展成3D网络结构。
[Abstract]:The potential applications of aromatic glycolic acid complexes with novel structures in the fields of drug delivery, molecular recognition, gas adsorption and separation have attracted more and more attention. In this paper, 17 novel complexes with transition metals and rare earth metals were synthesized based on tribiphenyl 3'5'5 '-tetracarboxylic acid ligands. The complexes were characterized by X-ray single crystal diffraction, IR, TGA and powder diffraction. The fluorescence properties of complexes 1: 8, 12 and 14 were analyzed, and the magnetic properties of complexes 2, 3, 3, 5, 6, 7, 7, 9 and 10 were studied. Complex 1 has good detectability for p-nitroaniline, while complex 8 is more selective for p-nitrotoluene, and complex 14 has good detectability for p-nitroaniline. 閰嶅悎鐗，
