摘要:
Three lanthanide-metal organic frameworks, namely, [Ln(2)(H2L)(DMF)(2)(H2O2)(2)]center dot 4H(2)O[Ln = Tb (1); Eu (2); Gd (3)] have been prepared and structurally characterized. Isostructural Ln-MOFs (1)-(3) display unique 3D frameworks with (4(12).6(3)) topology. Remarkably, Ln-MOFs (1) and (2) show intense characteristic red and green emissions and long lifetimes thanks to the "antenna" linker of H2L6- anions. Codoped Eu/Tb-MOFs (4)-(12) were synthesized by varying the Eu3+:Tb3+ stoichiometry. More importantly, such codoped Eu/Tb-MOF material emits multiple emission colors by enhancement and quenching of different Ln(3+) centers, which could applied to potential barcode materials. In addition, by adjusting different excitation wavelengths, the luminescence control of codoped Eu/Tb-MOFs (4)-(12) is achieved.
