【摘要】 采用溶剂热法合成了锶的配聚物[Sr2(p-BrPhHIDC)2(H2O)2]n(p-BrPhH3IDC=2-(对溴)苯基-4,5-咪唑二羧酸),进行了元素分析、红外光谱的表征,X射线单晶衍射结果表明它是一个二维的固态结构.采用TGA进行了配合物在空气气氛下的失重分析,发现在212.6℃以后,首先失重4.19%,说明配合物在212.6℃内是热稳定的.采用荧光光度法研究了其固态荧光性能,发现在325 nm处产生有发射光谱,原因是金属锶离子与有机配体形成配聚物增大了刚性所致.更多还原

【Abstract】 A two-dimensional coordination polymer,[Sr2( p-BrPhHIDC)2( H2O)2]n( p-BrPhH3IDC =2-( p-bromophenyl)-1H-imidazole-4,5-dicarboxylic acid) was solvothermally prepared,and structurally characterized by elemental analysis and infrared spectroscopy. The single crystal X-ray diffraction showed that Sr2 +atoms were connected by p-BrPhHIDC2-ligands to form a 2D solid-state structure. The weightlessness analysis of the complex in air was determined by thermogravimetric method. After heating to212. 6 ℃,the first weight loss of 4. 19% could be observed,which indicated that the complex was stable below 212. 6 ℃. The solid-state fluorescence was studied by fluorescence spectrophotometry,and found that the emission peak of the complex was located at 325 nm. It was due to the interactions between the Sr atoms and organic ligands which increased the rigidity of the coordination polymer.更多还原
