“…We have thus thermally dehydrated these compounds. As shown previously, [17,[19][20][21] dehydration of 1-Er provokes the collapse of the molecular framework and leads to a quasiamorphous phase with chemical formula [Er(btc)] that reversibly binds water to reform 1-Er. Despite great efforts, this phase has not yet been structurally characterized.…”

“…The yields of the reactions were close to 100 %. FTIR spectra show the expected strong characteristic absorptions for the symmetric and asymmetric vibrations of benzenedi (tri) The results of the elemental analysis of the heterodinuclear coordination polymers are summarized in Tables 4 and 5 The obtained microcrystalline powders were all assumed to be respectively isostructural to the previously described compounds [Er(btc)(H 2 O) 5 ·3.5H 2 O] ϱ , [16] [Er 2 (bdc) 3 21] on the basis of their X-ray powder diffraction diagrams. The homogeneity of the heterodinuclear samples was checked by SEM measurements.…”

International audienceThe near-IR luminescence properties of two ErIII-containing coordination polymers, namely, [Er(btc)(H2O)5·3.5H2O] [(btc)3– = 1,3,5-benzenetricarboxylate] and [Er2(bdc)3- (H2O)4] [(bdc)2– = 1,4-benzenedicarboxylate] were investigated with the aim of testing their potential use as optical materials. Because both present relatively small quantum yields and short excited-state lifetimes, factors influencing their luminescent properties were deciphered in an effort to improve their luminescent properties. Thus, three other families of compounds were also investigated: (i) the two corre-sponding dehydrated compounds with respective chemical formula [Er(btc)] and [Er2(bdc)3] for evaluating the importance of O–H vibrators, (ii) the heterodinuclear compounds [Er2–2xY2x(bdc)3(H2O)4] (x = 0.2, 0.5, 0.8 and 0.9) for estimating the role of intermetallic quenching and (iii) the heterodinuclear compounds [Er2–2xYb2x(bdc)3(H2O)4] (x = 0.2 and 0.5) for checking whether YbIII-sensitized up-conversion can be induced or not.

“…For these reasons, numerous lanthanide-containing coordination polymers involving such ligands have been reported. Great attention has particularly been devoted to lanthanide terephthalate coordination polymers, [25][26][27][28][29][30] because the terephthalate rodlike ligand is nontoxic and commercially available at low cost (see Scheme 1). Scheme 1.…”

Heteronuclear lanthanide terephthalate coordination polymers with the general chemical formula [Ln2–2xLn′2x(bdc)3(H2O)4]∞, for which bdc2– symbolizes benzene‐1,4‐dicarboxylate (or terephthalate) and Ln and Ln′ represent trivalent rare earth ions, were synthesized and structurally characterized. Analysis of the Y/Lu compounds by 89Y and 13C solid‐state NMR spectroscopy was carried out, and the results support the hypothesis of randomly distributed lanthanide ions. The spectroscopic and colorimetric properties of this family of compounds were investigated in detail. The resulting data demonstrate that this series of compounds presents highly tunable luminescence properties and clearly indicate that intermetallic deactivation processes play an important role in the emission mechanism. Playing with intermetallic distances allows one to tune the color and the brightness of the lanthanide emission in these coordination polymers.

“…[1][2][3][4][5][6][7][8][9] This renewal of interest is mainly due to their potential interest for depollution or gas storage purposes. Some of us are currently studying lanthanide-containing coordination polymers, aiming for materials exhibiting porosity [10][11][12][13] or interesting luminescent properties [14][15][16] and are respectful of the environment. Therefore, for more than ten years we have been developing a green synthetic strategy [17] employing water as solvent, non toxic reagents, high-yielding reactions conducted at ambient temperature and pressure, and gel media for crystal growth.…”

International audienceReactions in water between the disodium salt of 5-amino-1,3-benzenedicarboxylic acid or 5-aminoisophthalate (Na2aip) and lanthanide chlorides lead to two families of coordination polymers with the respective general chemical formulae {[Ln6(aip)7(H2O)24]*2(aip)*6H2O}∞ in which Ln = Tm or Yb (Family 1) and {[Ln2(aip)2(H2O)10]*(aip)*4H2O}∞ in which Ln = La-Er (except Pm) or Y (Family 2). Compounds belonging to Family 1 are isostructural. The crystal structure has been solved for the Er-containing compound. This compound crystallizes in the monoclinic system, space group P21/n (n°14) with a = 13.3439(3) Å, b = 27.3332(8) Å, c = 15.7191(4) Å, β = 97.90(1)°, V = 5680.41(82) Å3 and Z = 4. The crystal structure can be described as the juxtaposition of double helicoidal chains. Additional aminoisophthalate ions insuring the electroneutrality of the network are lying in the interchain space. Compounds belonging to Family 2 are isostructural. The crystal structure has been solved for the Eu-containing compound. This compound crystallizes in the monoclinic system, space group Pn (n°7) with a = 11.3427(2) Å, b = 10.6663(1) Å, c = 15.1639(3) Å, β = 97.8998(9)°, V = 1817.19(5) Å3 and Z = 2. The crystal structure can be described as the juxtaposition of zigzag double chains. Additional aminoisophthalate ligands are lying in the interchain space insuring the electroneutrality of the network. The luminescent properties under UV irradiation of these compounds have been explored. In particular, quantum yields, lifetimes and colorimetric coordinates of the Tb-, the Sm-, and the Dy-containing coordination polymers have been determined
