A Multifunctional Tb-MOF Detector for H₂O₂, Fe³⁺, Cr₂O₇ ^2-, and TPA Explosive Featuring Coexistence of Binuclear and Tetranuclear Clusters.

ABSTRACT: A novel three-dimensional microporous terbium(III) metal-organic framework (Tb-MOF) named as [Tb₁₀ (DBA)₆(OH)₄(H₂O)₅]·(H₃O)₄ (1), was successfully obtained by a solvothermal method based on terbium nitrate and 5-di(2',4'-dicarboxylphenyl) benzoic acid (H₅DBA). The Tb-MOF has been characterized by single crystal X-ray diffraction, elemental analysis, thermogravimetry, and fluorescence properties, and the purity was further confirmed by powder X-ray diffraction (PXRD) analysis. Structural analysis shows that there are two kinds of metal cluster species: binuclear and tetranuclear, which are linked by H₅DBA ligands in two μ₇ high coordination fashions into a three-dimensional m
