Antibiotics have successfully been developed and used widely in clinical therapeutics for many years to treat bacterial infections, resulting in their unregulated discharge into waterbodies, which adversely affects the flora and fauna. This triggers alarming health issues that ascertain the need to develop suitable sensors for the detection and removal of persitent antibiotic pollutants. Several reports have been made on lanthanide‐based luminescent metal‐organic frameworks (MOFs) as one of the best‐known chemosensors that render efficient and selective detection of antibiotics owing to their intrinsic luminescent response. Herein, the recent advancements in lanthanide‐based MOFs for recognizing antibiotics are reviewed with a detailed discussion on the mechanistic routes of detection. Also, the possible transitions between the energy levels of lanthanides and the unique photophysical attributes of lanthanide‐organic hybrids are critically assessed. Further, the performance of the reported chemosensors based on their detection range, the limit of detection, stability, reproducibility, and practical feasibility are extensively explored. These unique aspects of this review provide a solid prospect for designing innovative and ingenious fluorescent probes.

“…Electrochemiluminescence (ECL), integrating the unique properties of electrochemistry and chemiluminescence, does not require external light source excitation with the characteristics of high sensitivity and fast response. − Therefore, ECL is considered as a promising method for trace substance detection in analytical chemistry, which has been widely applied in many fields such as environmental monitoring, biomedical analysis, and food safety. − However, the reported luminophores in these ECL studies were mainly based on single-wavelength emission, severely limiting the development of multicolor ECL basic theory, which is far from meeting the needs of ECL applications. Satisfyingly, new materials with high porosity and catalysis are constantly emerging − and their ingenious applications provide a new perspective to design of high-efficiency multicolor ECL luminophores.…”

Currently, studies on electrochemiluminescence (ECL) mainly focused on the single emission of luminophores while those on multi-color ECL were rarely reported. Here, a bimesoporous composite of the metal−organic framework (MOF)/ covalent-organic framework (COF) with strong and stable dual-color ECL was prepared to construct a novel ECL sensor for sensitive detecting targets. A PTCA-COF with excellent ECL performance was loaded with a great amount of another ECL emitter Cu 3 (HHTP) 2 . Remarkably, the integrated composite had both ECL properties of PTCA-COF at 520 nm and Cu 3 (HHTP) 2 at 600 nm wavelengths. Furthermore, Cu 3 (HHTP) 2 with good electron transfer ability can greatly enhance the electrical conductivity and promote electrochemical activation. Thus, the simultaneous enhanced two-color ECL intensity and the catalytic properties of the conductive MOF exerted a dual enhancement effect on the ECL signal of the composite. Significantly, diclazepam can not only be adsorbed well on the multistage porous structure MOF/COF composite by π−π interactions but also selectively quench the ECL signal of the PTCA-COF, realizing the sensitive detection. The ECL sensor showed a wide detection range from 1.0 × 10 −13 to 1.0 × 10 −8 g/L, and the limit of detection (LOD) was as low as 2.6 × 10 −14 g/L (S/N = 3). The proposed ECL sensor preparation method was simple and sensitive, providing a new perspective for the potential application of multi-color ECL in the sensing field.
