Abstract

Abstract: Effective detection of organic/inorganic pollutants, such as antibiotics, nitro‐compounds, excessive Fe 3+ and MnO4 −, is crucial for human health and environmental protection. Here, a new terbium(III)–organic framework, namely [Tb(TATAB)(H2 O)]⋅2H2 O (Tb‐MOF, H3 TATAB=4, 4′, 4′′‐ s ‐triazine‐1, 3, 5‐triyltri‐ m ‐aminobenzoic acid), was assembled and characterized. TheTb‐MOF exhibits a water‐stable 3D bnn framework. Due to the existence of competitive absorption, Tb‐MOF has a high selectivity for detecting Fe 3+, MnO4 −, 4‐nirophenol and nitroimidazole (ronidazole, metronidazole, dimetridazole, ornidazole) in aqueous through luminescent quenching. The results suggest thatTb‐MOF is a simple and reliable reagent with multiple sensor responses in practical applications. To the best of our knowledge, this work represents the first Tb III ‐based MOF as an efficient fluorescent sensor for detecting metal ions, inorganic anions, nitro‐compounds, and antibiotics simultaneously. Abstract : Getting more responses : Multi‐responsive luminescent sensing for the recognition of different analytes at the molecular level is achieved using a Tb III ‐based metal–organic framework (Tb‐MOF ).
