“…[221] Three Ln-MOFs with the formula [Ln 2 (IMBA) 6 (dmp) 2 ] (IMBA = 4-iodo-3-methylbenzoic acid; dmp = 4,7-dimethyl-1,10-phenanthroline; Ln = Eu 3+ ; Ln = Gd 3+ ; Ln = Tb 3+ ) were synthesized. [222] Eu-MOF showed a very selective and sensitive response toward Fe 2+ , which can be visually observed with limit of detection of 1.0 × 10 −6 M. Further in-depth research shows that the sensing of Fe 2+ would not be disturbed by Fe 3+ or other species. [222] Recently a chromophoric ligand (2,2′-((4carboxyphenyl)azanediyl)diacetic acid (H 3 CPADA)) that can covalently bind to lanthanides and enhance its fluorescence intensity was fabricated.…”

Metal-organic frameworks (MOFs) are of great interest to researchers in chemistry and material science due to their various chemical and physical properties, which include high surface area, augmented adsorption/desorption kinetics, biocompatibility, and functional tunability. The structurally diverse 1-D, 2-D, and 3-D metalorganic frameworks have found applications in chemical sensing and several other fields, such as energy applications, biomedicine, and catalysis. In this review article, we address recent research advances in the use of metal-organic-framework-based nanocomposite materials as luminescent sensors for detecting various metal ions in aqueous biological and environmental samples.

“…Lanthanide complexes 1a–1c were synthesized with solvothermal method by heating a mixture of Ln(NO 3 ) 3 ·6H 2 O (Ln=Eu, Gd, Tb), dmp and IMBA at a molar ratio of 1:1:1.5 at 333 K for 120 h. The colorless block single crystals of 1a–1c were collected by filtration, and mounted on a glass fiber [1] .…”

In this data article, we present the FT-IR and PXRD data of the lanthanide complexes constructed by 4-iodo-3-methylbenzoic acid (IMBA) and 4,7-dimethyl-1,10-phenanthroline (dmp). Detailed structure analysis, luminescence and sensing properties were discussed in our previous study, “Highly Luminescent Lanthanide Complexes as Bifunctional Sensor for Et2O and Fe2+” (Zhao et al., 2018). Also, the data include the bond lengths and angles of [Ln2(IMBA)6(dmp)2] (Ln=Eu3+, 1a; Ln=Gd3+, 1b; Ln=Tb3+, 1c).

The development of visual and multifunctional sensors, and further the fabrication of portable sensing devices is of great importance. Herein, two dinuclear lanthanide clusters are designed, and their accurate molecules are determined to be [Ln2(DFBA)6(dmp)2(H2O)2] (Ln3+ = Eu3+ (1‐Eu) or Tb3+ (1‐Tb), HDFBA = 3,4‐difluorobenzoic acid, dmp = 4,7‐dimethyl‐1,10‐phenanthroline), by single‐crystal X‐ray diffraction. Interestingly, 1‐Eu shows rapid detection of ferrous ions (Fe2+) and acetylacetone (acac), with the limit of detection (LOD) as low as 5.6 and 1.0 ppb, respectively. LOD of 5.6 ppb for Fe2+ is far lower than the standard of World Health Organization (0.3 ppm, SDWA) and Chinese rural water quality standards (0.5 ppm, GB25467‐2010) for drinking water. As far as it is known, 1‐Eu is the most sensitive chemosensor for the detection of acac; the sensing can be discriminated by the naked eyes under 365 nm UV light. Furthermore, portable sensing devices of agarose gel, test paper, and sprayed films on plastic tube, glass, coin, test paper, stone, leaf, carbon rod, and iron sheet surfaces, based on 1‐Eu solution, are fabricated by facile methods, with visual and quick detection of Fe2+ in water under various conditions, and show excellent recyclable sensing performance for acac vapor.
