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{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 enables it to efficiently extract the natural product anthocyanins from the blackberries and can be released rapidly in NaCl aqueous solution. And, the nature of anionic framework makes it very sensitive to detect the cationic methyl viologen (MV2+) with a detection limit as low as 1 × 10-8 M.
