“…In the presence of the sulfide anion, the intensity of the ligand-centered emission decreases, whereas the intensity of the Eu 3+ emission increased with the increase of I 615 / I 393 value to 4.16. This is due to the strong interaction between the soft Cu 2+ ion with soft sulfide anions (Pearson’s theory) to form a stable CuS ( K sp = 6.3 × 10 –36 ) species that revived the strong antenna effect between H 4 btec and Eu 3+ ion (Figure ).…”

In the last two decades, metal−organic frameworks (MOFs) have appeared as new multifunctional materials that show a variety of framework architectures depending on the choice of metal ions and ligands. Among several features that have been displayed by MOF, one of the important properties is its luminescent behavior that can arise from the ligand unit, metal ions, or the cavity guest molecules. Ratiometric fluorescence (RF) sensors can be made by changing the fluorescence intensity of emission peaks associated with multiemission probes, but the synthesis of such materials is always a challenge, as it requires multifluorescence groups having the same excitation with diverse emission wavelengths. In the case of MOFs, such features can be included by modifying the ligand unit and selecting the suitable metal ions or by using a desired guest molecule. As a result, MOF can act as a promising candidate for the construction of ratiometric fluorescence (RF) sensors. Thus, our aim in this review is to summarize some of the recent development that has been done in terms of synthesis, mechanism, and applications of ratiometric sensors by using MOF materials.

“…As shown in Table , comparing the detection limit with results from the literature, the complexes 3 and 6 in this work exhibit lower detection limits (1.0 × 10 −3 and 1.1 × 10 −3 , respectively) than those of previously reported, suggesting that the prepared salen‐type lanthanide coordination polymers could be applied to be a convenient and highly sensitive detection of formaldehyde. It is worth noting that luminescent properties of coordination polymers (CPs) are very sensitive to pH, because the different concentration of acids or bases buffered solution may react with metal ions to ruin the CPs framework, or the CPs may be directly dissolved in the buffered solution, which in turns affects the formaldehyde sensitive detection . An example of MOF‐253‐Eu‐TTA luminescent sensor, the Eu 3+ characteristic luminescence intensity is almost unchanged at pH 5–7 due to its stable structure.…”

Reactions of N,N'-bis (salicylidene)-1,2-cyclohexanediamine (H L) with mixed lanthanide counterions of LnCl ·6H O and Ln (NO ) ·6H O afford six H L lanthanide coordination polymers, e.g. {[Pr(H L) (NO ) Cl]·2CH Cl } (1); {[Ln(H L) (NO ) ] ·5CHCl ·mCH OH} [Ln = Sm (2), Eu (3), Gd (4), Tb (5) and Yb (6); m = 1 (2-5); m = 0 (6)]. X-ray crystallographic analysis reveals that complex 1 exhibits three-dimensional diamondoid topologic structure and complexes 2-6 are of two-dimensional structure. Luminescent spectra show that complexes 1 and 6 have characteristic near-infrared (NIR) emission of praseodymium (III) and ytterbium (III) ions and complexes 2-5 emit luminescence in the visible region. Complexes 3 and 6 reveal sensitive luminescence responses to formaldehyde.

“…With the development of the dual‐ligand fluorescent probe, dual‐ligand coordination polymers can more easily achieve multi‐signal coordination and enhance the detection signal of the target. The dual ligands are linked to the ligand polymer molecules by synergistic coordination, which makes the coordination between the analyte and the dual‐ligand coordination polymer nanoparticles (CPNPs) more stable, sensitive, and highly selective [22].…”

As an effective ingredient of disinfectants, ClO À inevitably remains in water, which induces potential health hazards such as lung damage and kidney disease. In this study, we synthesized stimulus-responsive dual-ligand luminol-Tb-GMP coordination polymer nanoparticles (luminol-Tb-GMP CPNPs) as highly selective fluorescent probes for the real-time and visual detection of ClO À . CPNPs consist of Tb 3+ , a nuclear metal, that coordinates with GMP and luminol, an auxiliary ligand. GMP can be oxidized by ClO À and damage its structure, resulting in fluorescence quenching of CPNPs. The two-ligand CPNPs sensor has a rapid fluorescent response, significant fluorescent color change, and high sensitivity, with a linear range of 2-18 μM and a detection limit of 0.14 μM. It has been successfully used to detect ClO À in tap water, fountain water, and drinking water. Simultaneously, the portable filter paper strip was prepared to expand the range of applications outside the laboratory, which will provide a promising application for the real-time and semiquantitative analysis of ClO À .
