“…It is interesting to note that no specific interactions, such as π–π stacking or hydrogen bonding, were found between the layers of NIIC‐1‐Ln , which are packed along the crystallographic axis c (Figure 1d). These features of NIIC‐1‐Eu and NIIC‐1‐Tb are very different from the recently reported La 3+ ‐based coordination polymer with the same ligand, {[La(HL)(H 4 L)(H 2 O) 4 ]⋅2H 2 O} n , the structure of which resembled 1D chains joined by multiply π–π stacking and hydrogen bonding interactions into a 3D supramolecular network [27] …”

[27] Infrared spectroscopy results show that the main characteristic absorption peaks of the H 4 L ligand are present in the spectra of NIIC-1-Tb and NIIC-1-Eu (Figure S2). The thermogravimetric analysis of NIIC-1-Tb and NIIC-1-Eu shows that both of them loose the coordinated water molecules in the temperature range from 80 to 140 °C (Figure S3).…”

Solvothermal reaction of 5,5′‐(pyridine‐2,6‐diylbis(oxy))diisophthalic acid (H4L) with europium(III) or terbium(III) nitrates in acetonitrile‐water (1 : 1) at 120 °C gave rise to isostructural 2D coordination polymers, [Ln(HL)(H2O)3]∞ (NIIC‐1‐Eu and NIIC‐1‐Tb), the layers of which are composed by eight‐coordinated lanthanide(III) ions interconnected by triply deprotonated ligands HL3−. The layers are packed in the crystal without any specific intermolecular interactions between them, allowing the facile preparation of stable water suspensions, in which NIIC‐1‐Tb exhibited top‐performing sensing properties through luminescence quenching effect with exceptionally low detection limits towards Fe3+ (LOD 8.62 nM), ofloxacin (OFX) antibiotic (LOD 3.91 nM) and cotton phytotoxicant gossypol (LOD 2.27 nM). In addition to low detection limit and high selectivity, NIIC‐1‐Tb features fast sensing response (within 60–90 seconds), making it superior to other MOF‐based sensors for metal cations and organic toxicants. The photoluminescence quantum yield of NIIC‐1‐Tb was 93 %, one of the highest among lanthanide MOFs. Mixed‐metal coordination polymers NIIC‐1‐EuxTb1−x demonstrated efficient photoluminescence, the color of which could be modulated by the excitation wavelength and time delay for emission monitoring (within 1 millisecond). Furthermore, an original 2D QR‐coding scheme was designed for anti‐counterfeiting labeling of goods based on unique and tunable emission spectra of NIIC‐1‐Ln coordination polymers.

“…The same ligand was used with Tb recently to give a highly stable and luminous probe material with 93% quantum yield that exhibited top performance sensing towards ofloxacin (OFX). [138] Similar transition of Tb was observed for the hybrid material and a concentration dependent detection signal was observed for OFX. At lower concentrations, a significant electron transfer was evident from the energy level diagrams and at higher concentrations, IFE was evidenced.…”

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.

“…Lanthanide ions are often used as luminescent sources due to the characteristic emission and high luminescence efficiency. [31][32][33] The other situation is where the luminescence is produced by the interaction between the host and the guest. The luminescence mechanism of LMOFs is mainly charge transfer and energy transfer processes.…”
