A 3D CaII-based anionic metal–organic framework (Ca-MOF) with microporous pores containing [(CH3)2NH2]I cations has been synthesised. The Ca-MOF possesses a formula of [(CH3)2NH2]2[Ca5(TATB)4(DMA)4](DMA)10(H2O)2 (H3TATB=4,4′,4″-s-triazine-2,4,6-triyltribenzoic acid, DMA=N,N-dimethylacetamide) with 12-connected [Ca5(O2CR)10] secondary building units and 3-connected TATB ligands to give a rare 12,3-connected net of llj topology. Furthermore, the postsynthetic material (TbIII@Ca-MOF), which is obtained by ion-exchange processes, exhibits an excellent ability for the recyclable detection of CrIII and FeIII ions.

Combination of a non-planar tripodal ligand 3,4-bi(4-carboxyphenyl)-benzoic acid (H3L) and Zn5O4-cluster secondary building units affords a highly connected three-dimensional metal–organic framework, {[Zn5(μ3-OH)3(μ2-OH)L2(H2O)2](H2O)2}n (1), which exhibits an unusual (3,4,9)-connected (42.5)(3.43.52)(32.45.511.613.73.82) topological net. The thermal stability and solid luminescence of the crystalline material have also been investigated.

Sesamol, is well-known antioxidant and can reduce the rate of oxidation and prolong expiration date. It is also potentially antimutagenic and antihepatotoxic, the detection of sesamol is important and remains a huge challenge. Herein, a new 3D alkaline earth Sr metal organic framework [Sr(BDC)DMACH2O]n (BDC = benzene-1,4-dicarboxylate; DMAC = N,N-dimethylacetamide) is synthesized and a probe based on Tb3+ functionalized Sr-MOF. The Tb(3+)@Sr-MOF showed good luminescence and thermal property. Due to the energy competition between sesamol and ligand, the luminescence intensity of sesamol increases meantime luminescence intensity of Tb3+ decreases, the ratio of the emission intensities (I344/I545) linearly increases with sesamol in concentrations ranging from 1 × 10−7 to 8 × 10−4 M. Furthermore, the fluorescence-detected circular test shows that the composite Tb(3+)@Sr-MOF can serve as ratiometric sensor for sensing of sesamol. This is the first example for self-calibrated detecting sesamol based on metal-organic framework (MOF).
