A series of isostructural three-dimensional metal-organic frameworks Pr(2)(N-BDC)(3)(dmf)(4) (1), {[Eu(2)(N-BDC)(3)(dmf)(4)] x 2DMF}(infinity) (2 x 2DMF), Gd(2)(N-BDC)(3)(dmf)(4) (3), {[Tb(2)(N-BDC)(3)(dmf)(4)] x 2DMF}(infinity) (4 x 2DMF), {[Dy(2)(N-BDC)(3)(dmf)(4)] x 2DMF}(infinity) (5 x 2DMF) (N-H(2)BDC = 2-amino-1,4-benzenedicarboxylic acid; DMF = N,N'-dimethylformamide) with cubic 4(12) x 6(3) topology have been synthesized using solvothermal conditions. The networks were generated via formation of a dinuclear Ln(2) secondary building block, involving the dicarboxylate ligand as a bridge. The luminescent properties of the Tb(III) and Eu(III) complexes were studied and showed characteristic emissions at room temperature. Antiferromagnetic interactions between Ln(III) ions were observed from magnetic susceptibility data.
通过溶剂热条件合成了一系列具有立方4(12)×6(3)拓扑结构的同构三维金属有机骨架Pr(2)(N-BDC)(3)(dmf)(4) (1)、{[Eu(2)(N-BDC)(3)(dmf)(4)]×2DMF}(无穷大) (2×2DMF)、Gd(2)(N-BDC)(3)(dmf)(4) (3)、{[Tb(2)(N-BDC)(3)(dmf)(4)]×2DMF}(无穷大) (4×2DMF)、{[Dy(2)(N-BDC)(3)(dmf)(4)]×2DMF}(无穷大) (5×2DMF)(N-H(2)BDC = 2-氨基-1,4-苯二甲酸;DMF = N,N'-二甲基甲酰胺)。这些网络是通过形成双核Ln(2)二级结构单元生成的,其中二羧酸配体作为桥连。研究了Tb(III)和Eu(III)配合物的发光性质,结果表明它们在室温下有特征发射。从磁化率数据观察到Ln(III)离子之间的反铁磁相互作用。
