通过金属配体定向组装己羧酸单元和Tb3+离子，合成了阴离子型沸石-金属-有机骨架[(CH3)(2)NH2](9){Tb-6(eta(6)-TATAT)(4)(H2O)(12)}中心点3Cl中心点DMA中心点7H2O [1，h (6)TATAT = 5,5′，5′-（1,3,5三嗪-2,4,6-三基三氨基）- 1,3-苯二羧酸]。化合物1具有超大空腔，能有效地从黑莓中提取天然产物花青素，并将其快速释放到NaCl水溶液中。阴离子框架的性质使其对阳离子甲基紫素（MV2+）的检测非常敏感，检测限低至1中心点10(-8)M。
An anionic sod-type zeoliticmetal-organic framework [(CH3)(2)NH2](9){Tb-6(eta(6)-TATAT)(4)(H2O)(12)} center dot 3Cl center dot DMA center dot 7H2O [1, H(6)TATAT = 5,5',5 ''-(1,3,5triazine-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 center dot 10(-8) M.
