“…There was no significant change in the luminescence lifetimes before and after the addition of OFX, suggesting a static quenching mechanism, in which the interaction with the analyte takes place in the ground state. [60][61][62] No effective overlap between the UV absorption spectra of OFX and the emission spectrum ofb NIIC-2-Tb suggests that the cause of the luminescence quenching is not from Förster resonance energy transfer (FRET) (Figure 2h). [63][64][65] At the same time, an effective overlap between the UV absorption spectra of OFX and the excitation spectrum of NIIC-2-Tb shows that OFX compete for the absorption of the excitation light with NIIC-2-Tb leading to the quenching of luminescence, i.e., the internal filter effect (IFE) takes place (Figure 2h).…”

Highly selective and sensitive quantitative detection of ofloxacin (OFX) at ultra‐low concentrations in aqueous media and development of new afterglow materials remains a challenge. Herein, a new 2D water‐stable lanthanide metal‐organic framework (NIIC‐2‐Tb) is proposed, which exhibits high selectivity towards OFX through the luminescence quenching with the lowest detection limit (1.1 nM) reported to date and a fast response within 6 s. In addition, the luminescence detection of OFX by NIIC‐2‐Tb was not affected by typical components of blood plasma and urine. The excellent sensing effect of NIIC‐2‐Tb was further utilized to prepare a composite functional sensing carrageenan hydrogel material for the rapid detection of OFX in meat in real time and the first discovery of impressive afterglow in MOF‐based hydrogels. This study not only presents novel Ln‐MOF materials and Ln‐MOF‐based hydrogel films for luminescent sensing of OFX, but also demonstrates color‐tunable luminescent films with afterglow, which expands the application of composite luminescent materials for detection and anti‐counterfeiting.This article is protected by copyright.

Emerging contaminants have recently evolved into a severe worldwide environmental issue. Organophosphate flame retardants (OPFRs) with neurotoxicity, genotoxicity, and reproductive and developmental toxicity are a class of notorious emerging contaminants that cause great concern. The development of high-efficiency and portable sensors for rapid online monitoring of OPFRs has become the primary demand for the exploration of the environmental migration and transformation of OPFRs. In this work, interestingly, the cataluminescence (CTL) phenomenon of OPFRs is first observed, and an ingenious multidimensional ratiometric CTL sensing strategy is developed for the recognition of multiple OPFRs. Three characteristic ratios are extracted from the multipeak CTL spectral curves based on energy transfer of single Tb/Eu-modified MgO sensing material, and thus a novel threedimensional (3D) code recognition could be mapped out. This obtained 3D coordinate is found to be a unique characteristic for a given OPFR, just like an exclusive person's ID number, which can successfully discriminate and detect 10 kinds of OPFR vapors, including homologous series and isomers. More importantly, CTL mechanism investigations for OPFRs demonstrate that OPFRs undergo a series of chemical reaction processes, e.g., oxidative pyrolysis and hydroxylation, and different high-energy excited intermediates are generated, which trigger discrepant energy-transfer efficiency toward rare earth ions, leading to multipeak spectral profiles. Briefly, this proposed CTL analytical platform for OPFRs recognition initiates a new sensing principle for the efficient identification of emerging contaminants and shows significant prospects on rapid on-site detection.
