Coordination polymers are constructed from metal ions and bridging ligands, linking them into solid-state structures extending in one (1D), two (2D) or three dimensions (3D). Two- and three-dimensional coordination polymers with potential voids are often referred to as metal-organic frameworks (MOFs) or porous coordination polymers. Luminescence is an important property of coordination polymers, often playing a key role in their applications. Photophysical properties of the coordination polymers can be associated with intraligand, metal-centered, guest-centered, metal-to-ligand and ligand-to-metal electron transitions. In recent years, a rapid growth of publications devoted to luminescent or fluorescent coordination polymers can be observed. In this review the use of fluorescent ligands, namely, 4,4′-stilbenedicarboxylic acid, 1,3,4-oxadiazole, thiazole, 2,1,3-benzothiadiazole, terpyridine and carbazole derivatives, naphthalene diimides, 4,4′,4′′-nitrilotribenzoic acid, ruthenium(II) and iridium(III) complexes, boron-dipyrromethene (BODIPY) derivatives, porphyrins, for the construction of coordination polymers are surveyed. Applications of such coordination polymers based on their photophysical properties will be discussed. The review covers the literature published before April 2020.

“…Various polar aprotic solvents with high boiling points, namely DMF ( N , N′ -dimethylformamide), DMA ( N , N′ -dimethylacetamide), DEF ( N , N′ -diethylformamide), DMSO (dimethyl sulfoxide), NMP ( N -methyl-2-pyrrolidone or 1-methylpyrrolidin-2-one), etc., have been used for the synthesis of coordination networks, especially of MOFs. , Among the aforementioned aprotic polar solvents DMA has been one of the least employed to date. − Additionally, systematic studies of their steric effects on the coordination behaviors of Ln 3+ centers are rather uncommon; hence, the first goal that we set out for this study is the determination of what the coordination steric effect of the ancillary DMA solvent is on the self-assembly of lanthanide(III) 2,5-thiophenedicarboxylates. To this end, we have prepared 13 highly related Ln-CPs, in which Ln = La–Lu except Pm and Tm, with the general formulas of [Ln 2 (2,5-TDA) 3 (DMA) 2 (H 2 O)] n (group A of Ln-CPs 1 – 4 ) and [Ln 2 (2,5-TDA) 3 (DMA) 2 ] n (group B of Ln-CPs 5 – 13 ), wherein 2,5-TDA 2– = 2,5-thiophedicarboxylate dianion and Ln = La ( 1 ), Ce ( 2 ), Pr ( 3 ), Nd ( 4 ), Sm ( 5 ), Eu ( 6 ), Gd ( 7 ), Tb ( 8 ), Dy ( 9 ), Ho ( 10 ), Er ( 11 ), Yb ( 12 ), Lu ( 13 ).…”

Thirteen new three-dimensional lanthanide(III)-2,5-thiophenedicarboxylate coordination polymers (Ln-CPs) with general formulas of [Ln2(2,5-TDA)3(DMA)2(H2O)] n (Ln-CPs 1–4) and [Ln2(2,5-TDA)3(DMA)2] n (Ln-CPs 5–13) (where 2,5-TDA2– = 2,5-thiophedicarboxylate dianion, DMA = N,N′-dimethylacetamide, and Ln = La (1), Ce (2), Pr (3), Nd (4), Sm (5), Eu (6), Gd (7), Tb (8), Dy (9), Ho (10), Er (11), Yb (12) Lu (13)) have been synthesized solvothermally under two different temperature conditions in a DMA–H2O mixed solvent system. A structural analysis discloses that the four Ln-CPs 1–4 crystallize in the orthorhombic space group Pna21, whereas the eight Ln-CPs 5–8 and 10–13 crystallize in the triclinic P̅1 space group and Ln-CP 9 (Dy) adopts the monoclinic P2/c space group. The distinct crystal structures and coordination features indicate that lanthanide contraction, ancillary DMA molecules, and different coordination modes identified for 2,5-TDA2– play deciding roles in the self-assembly of Ln-CPs 1–13. The Ln(III) centers in compounds 1–13 exhibit three different coordination numbers, 9 (only 1; around La1), 8 (1–8 and 10–12), and 7 (4, 8, 9 and 11–13) with monocapped-square-antiprismatic, bicapped-trigonal-prismatic, and monocapped-trigonal-prismatic geometries, respectively. The title compounds display distinct 3D coordination frameworks with dinuclear (La2O15; for 1 and Ln2O14; for 2–4) SBUs and tetranuclear [Ln4O28] SBUs (for compounds 5–13). Variable-temperature magnetic susceptibility measurements were investigated for Ln-CPs 7–11 with an applied dc field of 1 kOe. The weak antiferromagnetic interaction and small ligand/metal mass ratio make Ln-CP 7 (Gd) a good candidate for low-temperature magnetic refrigeration with an impressive −ΔS m max = 31.0 J kg–1 K–1 (63.6 mJ cm–3 K–1) at T = 2 K and ΔH = 7 T. Furthermore, the frequency and temperature dependences of the alternating current (ac) susceptibilities have been studied to explore the magnetic dynamics of Ln-CPs 8–10. Importantly, for compound 9 (Dy), the χ′m and χ″m curves and Cole–Cole plots at 2–6 K suggest the existence of slow magnetic relaxation behavior. Luminescence thermometry studies have been performed at 298–373 K for Ln-CPs 6 and 8. The Eu analogue (6) features a weak temperature dependence of luminescence lifetime (relative sensitivities of 0.43% K–1 and 0.34% K–1 at 298 and 373 K, respectively), whereas the Tb analogue (8) is a good lifetime-based luminescent thermometer with a constant relative sensitivity value of 1.35% K–1 in the investigated temperature range.

A new Cd(II) coordination polymer, {[Cd3(L)2(DMF)2(H2O)2]·H2O}n (H2L = 1,3-bisbenzyl-2-imidazolidine-4,5-dicarboxylic acid) was synthesized by one-pot synthesis method from 1,3-bisbenzyl-2-imidazolidine-4,5-dicarboxylic acid, NaOH, DMF, and Cd(NO3)2·4H2O. Its structure was determined by elemental analysis and single crystal X-ray diffraction. Structural analysis shows that three Cd(II) ions are all six-coordinated with four oxygen atoms of four 1,3-bisbenzyl-2-imidazolidine-4,5-dicarboxylate ligands and two O atoms from two DMF molecules (Cd1) or two oxygen atoms of two coordinated H2O molecules (Cd2 and Cd3) to form an octahedral coordination geometry. The Cd(II) coordination polymer displays a 1D chained structure by the bridging carboxylate groups from 1,3-bisbenzyl-2-imidazolidine-4,5-dicarboxylate ligands. The conversion of benzaldehyde is 90.9%, which is 40~50% higher than those of the other three aldehydes (4-methylbenzaldehyde, p-methoxybenzaldehyde and 3-chlorobenzaldehyde), so the Cd(II) coordination polymer catalyst shows better catalytic activity for the coupling reaction of benzaldehyde, phenylacetylene, and piperidine than the other three aldehydes.
