Anionic metal–organic framework for high-efficiency pollutant removal and selective sensing of Fe(iii) ions†
Abstract
An anionic metal–organic framework, (DMA)2[Y9(μ3-OH)8(μ2-OH)3BTB6]n·(solv)x (DMA = dimethylamine cation and BTB = 1,3,5-benzene(tris)benzoate), (gea-MOF-1), is a novel rare earth (RE) nonanuclear MOF with an unusual gea topology. It could be used as an adsorbent material for efficiently removing the cationic dye MB+. This MOF can not only emit strong fluroescence in MeOH suspension, but also serves as a fluorescent probe for selectively detecting Fe3+ among other metal ions through luminescence emission quenching.
