A luminescent metal-organic framework for highly selective sensing of nitrobenzene and aniline

摘要

A stable nonanuclear rare earth carboxylate cluster based metalorganic framework, (DMA)(2)[Y-9(mu(3)-OH)(8)(mu(2)-OH)(3)BTB6](n)center dot(solv)(x) (gea-MOF-1) (DMA = dimethylamine cation and BTB = 1,3,5-benzene(tris) benzoate) can act as a fluorescent sensor for highly sensitive and selective detection of nitrobenzene and aniline through fluorescence quenching. More importantly, the detection limit of nitrobenzene is on the 5-60 ppm scale.
