A Luminescent Ytterbium(III)-Organic Framework for Highly Selective Sensing of 2,4,6-Trinitrophenol

Publication date: Available online 14 March 2018 Source:Journal of Solid State Chemistry Author(s): Xuelian Xin, Minghui Zhang, Shijie Ji, Hanxiao Dong, Liangliang Zhang An ytterbium(III)-organic framework, [Yb4(abtc)3(HCOO) (H2O)]·(C2H8N) (H2O) (UPC-22, H4abtc = 3,3ʹ,5,5ʹ-azobenzene-tetracarboxylic acid) was synthesized under solvothermal conditions and characterized. UPC-22 exhibited strong H4abtc-based luminescence and can be used for sensing nitroaromatic compounds (NACs) in an ethanol suspension with outstanding selectivity and sensitivity. The most striking property of UPC-22 is its ability to selectively detect 2,4,6-trinitrophenol (TNP), thereby rendering it a promising TNP-selective luminescence probe. Graphical abstract
