摘要

Two isostructural lanthanide metal-organic frameworks [Ln-MOFs, Ln = Tb (1), Eu (8)] containing oxalic acid ligand with green, red luminescence were solvothermally synthesized. A series of Eu/Tb mixed MOFs (2-7), (C5H6N)(2)[EuxTb2-x(H2O)(2)(C2O4)(4)]center dot 2H(2)O, were designed and obtained, which displayed highly tunable luminescence color by adjusting the excitation wavelength. Complexes 1-8 were characterized by IR, elemental analysis, ICP, powder XRD, and TG measurements. The quantum yields of the complexes 1-8 range from 6.89 to 4.15%, whereas the fluorescence lifetime of 1-8 varies between 1.12 and 0.87 ms. Therefore, with the increase of the molar ratio of Eu, the quantum yields and fluorescence lifetime of the complexes 1-8 gradually decrease.
