A Eu( iii) metal–organic framework based on anthracenyl and alkynyl conjugation as a fluorescence probe for the selective monitoring of Fe 3+ and TNP. RSC Adv 2022; 12:26945-26952. [PMID: 36320831 PMCID: PMC9490770 DOI: 10.1039/d2ra02892a] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Accepted: 09/03/2022] [Indexed: 12/03/2022] Open
Abstract
In this work, a luminescent metal–organic framework (Eu-MOF {[Eu6L6(μ3-OH)8(H2O)3]8·H2O}n) was constructed by a solvothermal method with a linear organic ligand L (10-[(2-amino-4-carboxyl-phenyl)ethynyl]anthracene-9-carboxylic acid) based on anthracene and alkyne groups and using Eu3+ as the metal center. The MOF exhibits a stable UiO-66 crystal structure, and a six-core cluster twelve-linked secondary structural unit was successfully synthesized using 2-fluorobenzoic acid as a modulator, forming a classical fcu topology. Moreover, it exhibits good chemical stability. Interestingly, Eu-MOF exhibited high selectivity and sensitive fluorescence burst properties towards Fe3+ ions and 2,4,6-trinitrophenol (TNP) in DMF solution. For Fe3+, the KSV value is 5.06 × 105 M−1 and the LOD value is 5.1 × 10−7 M. For TNP, the KSV value is 1.92 × 104 M−1 and the LOD value is 1.93 × 10−6 M. In addition, Eu-MOF showed good anti-interference ability and fast response. This work provides an excellent fluorescent sensor for the detection of Fe3+ and 2,4,6-trinitrophenol (TNP) residues in contaminants. In this work, Eu-MOF has been synthesized and has excellent luminescence recognition ability for Fe3+ and TNP with good selectivity and high sensitivity via luminescence quenching.![]()
