Two basically isostructural lanthanide-based metal–organic frameworks (Ln-MOFs), {[Eu(dptz)(H2O)2]Cl·3H2O}n (JLNU-10-Eu, JLNU = Jilin Normal University) and {[Tb(dptz)(NO3)(H2O)]·7H2O}n (JLNU-10-Tb), have been successfully synthesized by employing 3-(3,5-dicarboxylphenyl)-5-(pyrid-2-yl)-1H-1,2,4-triazole (H2dptz) as a flexible carboxylic acid ligand through solvothermal reactions. Single-crystal structural studies on Ln-MOFs manifested that the compounds two-dimensional (2D) layered structure. Furthermore, fluorescence sensing experiments indicated JLNU-10-Eu JLNU-10-Tb had significant quenching effects Cr2O72–, Fe3+, TNP. It should be noted KSV value of in Fe3+ could reach 7.36 × 103, limit detection (LOD) was 0.57. The luminescence mechanism is discussed detail some relevant experiments. Additionally, series Ln-MOFs, JLNU-10-EuxTb1–x (x 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1), obtained simply regulating molar ratio Eu3+ Tb3+. Particularly, JLNU-10-Eu0.8Tb0.2 can achieve white light emission at an excitation wavelength 300 nm. CIE coordinates are (0.316, 0.332), which very approximate to ideal light. JLNU-10-Eu0.2Tb0.8 thermometer exhibits good linearity over temperature range 303–373 K with high sensitivity 4.1% K–1 373 K. construction multifunctional displays prospective applications fluorescent probes, light-emitting diodes, thermometers.
