摘      要：Three isomorphic Ln-MOFs[Ln(bcbob)(H_(2)O)(DMF)](Ln=Tb for 1,Eu for 2,Gd for 3;DMF=N,N-dimethylformamide)have been constructed from a semi-rigid V-shaped organic linker 3,5-bis((4 -carboxyl-benzyl)oxy)benzoilate acid(H3bcbob)under solvothermal conditions.X-ray single-crystal diffraction analysis re-veals that they exhibit a two-dimensional(2D)layered *** 1~3 show the characteristic green and red emissions of Ln^(3+)and blue emission arising from the organic ligand,*** on their photo-luminescence properties,the white-light emitting materials 4 and 5 with longer fluorescence lifetime(ms grade)and higher quantum yield(e.g.40.61%for 4)are ***,1 exhibits good sensing ability on ni-troaromatic compounds,especially for picric acid(PA).In addition,1 is still a highly selective sensing material for Fe^(3+)and Al^(3+).
