“…Hence, the main goal of this work was to probe a coordination ability of H 2 cpic toward metal(II) centers (Mn, Zn, and Cd) under hydrothermal conditions and to explore structural features and catalytic behavior of the obtained CPs. Notably, despite commercial availability, the existence of up to five coordination sites, and structural flexibility, the coordination chemistry of H 2 cpic still remains limited. − …”

This work explores an N,O-donor dicarboxylic acid, 5-(3-carboxyphenyl)picolinic acid (H 2 cpic), as an adjustable linker for generating diverse types of coordination polymers (CPs). Eight new compounds were hydrothermally assembled, completely characterized, and formulated as [Products 1−8 were assembled from H 2 O solutions containing the respective metal(II) chloride salts, H 2 cpic, NaOH, and an Ndonor crystallization mediator (optional: 1,10-phenanthroline, phen; or 2,2′-bipyridine, bipy). The structural types of 1−8 include a dimer complex (6), one-dimensional (1, 4, 5, 7, 8) and two-dimensional (2) CPs, and a three-dimensional (3) metal− organic framework. Hydrothermal reaction temperature, type of metal(II) center, and presence of mediators of crystallization are the factors responsible for structural diversity of 1−8. Thermal behavior, topological features, and catalytic properties of these products were studied. Notably, CP 1 acts as an effective, stable, and recyclable catalyst for the heterogeneous cyanosilylation of different aldehydes under mild conditions, resulting in quantitative conversion of aldehyde substrates to respective cyanohydrin products (99% product yields). Compounds 1−8 expand the usage of H 2 cpic for the assembly of functional coordination polymers, thus stimulating further research in this swiftly growing field.

“…Thus, Ln-CPs have attracted much attention due to their fascinating architectures and unique chemical and physical properties, especially their magnetic and optical properties. Up to now, many ligands have been utilized to construct multifunctional Ln-CPs (Silva et al, 2019;Song et al, 2019;Xiang et al, 2019). Among all types of ligands, aromatic polycarboxylic acids are the most frequently used due to their variety of coordination modes, as well as their structuring effects through -stacking (Shang et al, 2018;Wang et al, 2015).…”

Six two-dimensional (2D) coordination polymers (CPs), namely, poly[{μ5-3,3-[(5-carboxylato-1,3-phenylene)bis(oxy)]dibenzoato-κ6 O 1:O 1′:O 3,O 3′:O 5:O 5′}bis(N,N-dimethylformamide-κO)lanthanide(III)], [Ln(C21H11O8)(C3H7NO)2] n , with lanthanide/Ln = cerium/Ce for CP1, praseodymium/Pr for CP2, neodymium/Nd for CP3, samarium/Sm for CP4, europium/Eu for CP5 and gadolinium/Gd for CP6, have been prepared by solvothermal methods using the ligand 3,3′-[(5-carboxy-1,3-phenylene)bis(oxy)]dibenzoic acid (H3cpboda) in the presence of Ln(NO3)3. The complexes were characterized by single-crystal X-ray and powder diffraction, IR spectroscopy, elemental analysis and thermogravimetric analysis (TGA). All the structures of this family of lanthanide CPs are isomorphous with the triclinic space group P\overline{1} and reveal that they have the same 2D network based on binuclear LnIII units, which are further extended via interlayer C—H...π interactions into a three-dimensional supramolecular structure. The carboxylate groups of the cpboda3− ligands link adjacent LnIII ions and form binuclear [Ln2(RCOO)4] secondary building units (SBUs), in which each binuclear LnIII SBU contains four carboxylate groups from different cpboda3− ligands. Moreover, with the increase of the rare-earth Ln atomic radius, the dihedral angles between the aromatic rings gradually increase. Magnetically, CP6 shows weak antiferromagnetic coupling between the GdIII ions. The solid-state luminescence properties of CP2, CP5 and CP6 were examined at ambient temperature and CP5 exhibits characteristic red emission bands derived from the Eu3+ ion (CIE 0.53, 0.31), with luminescence quantum yields of 22%. Therefore, CP5 should be regarded as a potential optical material.

“…In the fluorescence titration experiments, the emission intensity of Eu 3+ ions at 617 nm gradually decreases and that of Htpbpc are observed to blue shift to 430 nm with increasing concentration of His from 10 –6 to 10 –3 M (Figure a). Afterward, the fluorescence quenching efficiency at 617 nm ( I 0 /I ) is quantitatively described by the Stern–Vomer (S–V) equation , at the range of low concentrations (Figure b). Obviously, the concentration of His has a good linear relationship with fluorescence quenching efficiency of Eu 3+ @Mn-MOF can be fitted to I 0 /I = 1144[M] + 0.9962 ( K sv = 1144 [M] −1 , R 2 = 0.993).…”

Due to the disruption by other nonanalyte factors, single-emission probes have been limited in complicated detecting systems. In this work, a pH-modulated luminescence chameleon system based on lanthanide-based MOF (Eu3+@Mn-MOF), with stable structure and miraculous dual-emitting fluorescent properties, was synthesized by a postsynthetic modification (PSM) strategy of a simple hydrothermal and agitation method. Amazingly, not only can the Eu3+@Mn-MOF emit a broad emission at 500 nm attributed to the ligand-based fluorescence emission but it can also exhibit the characteristic emission of Eu3+ ions responding to the antenna effect. Moreover, the Eu3+@Mn-MOF displays an interesting luminescence color transition between acidic and basic solutions. Inspired by this phenomenon, a pH-modulated luminescence chameleon system was first constructed and employed to detect histidine, a kind of basic amino acid for a variety of biological matters, causing a unique fluorescence signal of the ratio-dependent color to change from yellow to light pink which differs from the color change of other water-soluble amino acids. Therefore, Eu3+@Mn-MOF can be as a practical pH-modulated luminescence chameleon system chemsensor for sensing histidine with low detection limit, high sensitivity, and rapid sensing time. In conclusion, the postsynthetic modified Eu3+@Mn-MOF has outstanding applications in the fields of chemical detection and human health.
