摘要：

Two isostructural lanthanide MOFs, [Ln(3)K(2)(FHA)(4)(NO3)(3)(MeCH)(2)](n) (Ln = Eu 1, Tb 2) (H(2)FDA= furan-2,5-dicarboxylic acid), have been constructed under solvothermal conditions. Structures analyses demonstrate two complexes possess three-dimensional network with monoclinic space group C2/c. The topology analysis shows that the whole framework can be simplified to a 3,8T24 topology constructed from trinuclear {Ln(3)} as secondary building units (SBUs) without considering K+ ions. Solid state luminescent studies indicate that 1 and 2 show the characteristic red and green emissions of the corresponding Ln(3+) ions, respectively. The luminescence lifetimes of 1 and 2 are approximately 1.04 ms and 0.41 ms. In addition, activated 1 exhibits excellent fluorescence sensing for small molecules, especially for nitrobenzene.
