文摘

A series of isostructural three-dimensional metal-organic frameworks [Pr₂(N-BDC)₃(dmf)₄]_∞ (1), {[Eu₂(N-BDC)₃(dmf)₄]·2DMF}_∞ (2·2DMF), [Gd₂(N-BDC)₃(dmf)₄]_∞ (3), {[Tb₂(N-BDC)₃(dmf)₄]·2DMF}_∞ (4·2DMF), {[Dy₂(N-BDC)₃(dmf)₄]·2DMF}_∞ (5·2DMF) (N-H₂BDC = 2-amino-1,4-benzenedicarboxylic acid; DMF = N,N′-dimethylformamide) with cubic 4¹²·6³ topology have been synthesized using solvothermal conditions. The networks were generated via formation of a dinuclear Ln₂ 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.
