An anionic sod-type zeolitic metal–organic framework [(CH₃)₂NH₂]₉{Tb₆(η⁶-TATAT)₄(H₂O)₁₂}·3Cl·DMA·7H₂O [1, H₆TATAT = 5,5′,5′′-(1,3,5-triazine-2,4,6-triyltriimino)tri-1,3-benzenedicarboxylic acid] has been synthesized by metal–ligand directed assembly of hexacarboxylic acid units and Tb³⁺ ions. Compound 1 with extra-large cavities can efficiently extract natural product anthocyanins from blackberries and release them rapidly into NaCl aqueous solution. And, the nature of the anionic framework makes it very sensitive to detect cationic methyl viologen (MV²⁺) with a detection limit as low as 1 × 10⁻⁸ M.

阴离子草皮型MO-MOF，具有超大空腔，可有效提取花青素和检测甲基紫精†

阴离子草皮型沸石金属-有机骨架[（CH ₃）₂ NH ₂ ] ₉ {铽₆（η ⁶ -TATAT）₄（H ₂ O）₁₂ }··3CL DMA·7H ₂ -O [ 1，H ₆ TATAT = 5,5'，5'-（（1,3,5-三嗪-2,4,6-三基三亚氨基）三-1,3-苯二甲酸]是通过金属-配体定向组装的六羧酸单元合成的和Tb ³⁺离子。化合物1具有超大腔体的产品可以有效地从黑莓中提取天然产物花青素，并将其迅速释放到NaCl水溶液中。并且，阴离子框架的性质使其对阳离子甲基紫精（MV ²⁺）的检测限非常低，检测限低至1×10 ^-8M。
