An anionic sod-type terbium-MOF with extra-large cavities for effective anthocyanin extraction and methyl viologen detection

Abstract

An anionic sod-type zeolitic metal–organic framework [(CH3)2NH2]9{Tb66-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.
