“…With the use of lower temperature (120 °C) and shorter reaction time (24 h) relative to the conditions generally employed for the synthesis of LnCPs using mixed rigid and flexible polycarboxylates, − [Nd 2 (ad)(phth) 2 (H 2 O) 4 ] ( I ) and [Ln(ad) 0.5 (phth)(H 2 O) 2 ] ( II – VII ) have been synthesized. Despite the addition of DABCO, it is not included in the yielded complexes but acting as a weak base deprotonating the organic ligands’ carboxyl groups.…”

Based on the mixed phthalate (phth) and adipate (ad), [Nd(ad)(phth)(HO)] (I) and [Ln(ad)(phth)(HO)] (Ln = Eu (II), Gd (III), Tb (IV), Dy (V), Er (VI), Tm (VII), 1Eu:10Tb (VIII), 3Eu:10Tb (IX), and 5Eu:10Tb (X)) were synthesized and characterized. Complexes VIII-X show excellent ratiometric temperature sensing behavior in physiological and higher temperature ranges (303-423 K) rendered by the Tb-to-Eu energy transfer process. The efficiency of the process as illustrated through the lifetime measurements depends on both the Eu:Tb mole ratio and the temperature. The performance of X in terms of relative sensitivity ( S), temperature resolution, and measurement repeatability were determined, revealing the maximum S ( S) of 1.21%·K at 303 K with reliable temperature resolution and excellent repeatability.

“…There are several Ln-CPs with glutarate as a key organic linker reported up-to-date, such as {[Nd(H 2 O) 4 (glu)]Cl} n , and {[Nd 2 (H 2 O) 2 (glu) 3 ]·2H 2 O} n . Auxiliary organic ligands are often introduced into the coordination entity in order to promote the antenna effect, which directly coordinates to Ln 3+ cation and enhances Ln 3+ emission by using their intrinsic chromophore nature of the π-conjugated aromatic system, ,, such as in [Eu III (BSA)(glu)(H 2 O) 2 ] n [Ln = Eu, Sm, Ce, Pr, Nd; HBSA = benzenesulfonic acid], [Ln III (glu)(pic)(H 2 O) 2 ] n [Ln = Sm, Tb and Eu]; Hpic = picolinic acid], [Ln III 2 (H 2 O) 2 (ip)(glu) 2 ] n [Ln = Gd, Dy, Y; H 2 ip = isophthalic acid], and [Sm 2 (H 2 O) 2 (ip)(glu) 2 ] n . The lanthanide and group 3 element coordination polymers with glu 2– and 1,10-phenanthroline as auxiliary chelating ligands [Ln(phen)(glu)Cl] n [Ln = Y, Tm; phen = 1,10-phenanthroline], [Ln 2 (phen) 2 (glu) 3 ] n [Ln = Ce, Tb, Ho], and [La 2 (glu) 3 (H 2 O) 3 ] n exhibited the effects of auxiliary organic ligands on their photoluminescence properties .…”

A series of five isostructural 3D lanthanide-based coordination polymers [Ln III 2 (H 2 O) 6 (glu)(SO 4 ) 2 ] n [Ln = Pr(1), Nd(2), Sm(3), Eu(4), and Gd(5)] was effortlessly obtained within a few minutes via the microwave-heating method. The employment of auxiliary bases, that is, sodium hydroxide, 4,4′-bipyridine, and 1,4-diazabicyclo[2.2.2]octane, led to the formation of the title complex, whereas base-free synthesis yielded a three-dimensional inorganic coordination polymer, [Ln 2 (H 2 O) 4 (SO 4 ) 3 ] n •nH 2 O, Ln = Nd (2a). The robustness of the synthetic method was illustrated as both microwave-heating and conventional hydrothermal techniques also enabled the formation of a high-crystalline phase-pure complex 1−5. In the structure of 1−5, glutarato (glu 2− ) and sulfato ligands link dinuclear Ln(III) building units into three-dimensional frames. The glu 2− ligands act as tethering linkers, expanding the structure into a neutral 3D coordination network. Hydrogen bonds were found to be the predominant intermolecular interactions in the crystal structures. Photoluminescence of the complex 1−5 was studied.

“…27 Specifically, the -SO 3 H group has also been introduced through the aromatic linker of MIL-101 15 and several other MOFs. [31][32][33] It should be noted that most of the examples existing in the literature on the post-grafting of CUS and the post-covalent modification of organic ligands or linker sites show functionalized MOFs with limited stability while the functionalized MOFs by the pre-modification of organic linkers possess an improved stability. 15,28 In the current work, the sulfoxy or sulfonic acid-functionalized MIL-101 catalyst was prepared by either post-functionalization or the one-pot synthesis strategy.…”

The sulfoxy or sulfonic acid-functionalized MIL-101 catalyst was prepared by either post-functionalization or pre-modification of the organic linkers with the functionalized ligands, respectively, the latter is the so-called one-pot synthesis method. These catalysts were systemically characterized by XRD, N 2 adsorption, acid-base titration, and FT-IR techniques and applied in the liquid-phase esterification of monocarboxylic acids with monohydric alcohols. The results show that the sulfonic acid-functionalized MIL-101 (S-MIL-101) prepared by the one-pot synthesis method possesses a higher catalytic activity in the esterification than its counterpart the sulfoxy acid-functionalized MIL-101 (S/MIL-101) prepared by the post-functionalized method, due to the fact that S-MIL101 has a higher acid loading and a high utilization efficiency of the functionalized acid sites. Moreover, S-MIL-101 is stable to leaching, behaves as a true heterogeneous catalyst, can be easily recovered by filtration, and can be reused five times in succession without any loss of its catalytic activity.
