| 摘要: 溶剂热条件下采用呋喃-2,5-二羧酸和六水合硝酸镉为原料,合成出2个新的二维镉金属配位聚合物,[Cd2(FDC)2(DMA)2(DMF)]n (1)和[Cd3(FDC)3(DMF)4(H2O)]n (2)(H2FDC=呋喃-2,5-二羧酸,DMA=N,N-二甲基乙酰胺,DMF=N,N-二甲基甲酰胺)。通过元素分析、红外光谱、差热分析、X-射线单晶衍射等方法对配合物进行了结构表征。结果显示,配合物1和2均为二维网格状结构,通过分子间的C-H…O氢键作用构筑成三维超分子结构。化合物1和2常温固态下的荧光发射峰分别为501和476 nm,相比配体的荧光光谱,2个化合物均发生了红移现象。 |

| Abstract: Two new 2D cadmium(Ⅱ) coordination polymers, [Cd2(FDCA)2(DMA)2(DMF)]n (1) and [Cd3(FDC)3(DMF)4(H2O)]n (2) (H2FDC=2,5-furandicarboxylic acid, DMA=N, N-dimethylacetamide, DMF=N, N-dimethylformamide), have been successfully synthesized under solvothermal conditions and characterized by elemental analysis, IR-spectroscopy, thermogravimetric analysis, and single-crystal X-ray diffraction. The results reveal that both complexes 1 and 2 form 2D net structures, which are further linked to form 3D supramolecular structures via intermolecular C-H…O hydrogen bonding interactions. In solid state, 1 and 2 emit the intensely indigotin photoluminescence (501 and 476 nm) at room temperature. |
