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.

发光的（（III）-有机框架，用于2,4,6-三硝基苯酚的高选择性传感

III（III）-有机骨架，[Yb ₄（abtc）₃（HCOO）（H ₂ O）]·（C ₂ H ₈ N）（H ₂ O）（UPC-22，H ₄ abtc = 3,3ʹ在溶剂热条件下合成了（5,5,5′-偶氮苯-四羧酸）并进行了表征。UPC-22表现出基于H ₄ abtc的强发光，可用于感测乙醇悬浮液中的硝基芳香族化合物（NAC），具有出色的选择性和灵敏度。UPC-22最引人注目的特性是其选择性检测2,4,6-三硝基苯酚（TNP）的能力，从而使其成为有前途的TNP选择性发光探针。
