  abstract = {Oxalatoborates were transformed into dimeric spiro-borate complexes by abstraction of oxalate ligands by Lewis acidic lanthanide trichlorides. Oxalatoborates with different anions and cations were investigated containing either bis-oxalatoborate or catecholato-oxalatoborate anions and lithium as well as EMIM (1-ethyl-3-methyl-imidazolium) and BMIM cations (1-n-butyl-3-methyl-imidazolium) from the respective ionic liquids (ILs). Depending on the amount of oxalate groups and the different cations, the oxalate groups are partly or fully abstracted and transferred to the lanthanides. The reaction of anhydrous PrCl3 with Li[B(C6H4O2)(C2O4)] (lithium catecholato-oxalatoborate = Li[Catbox]) in pyridine (py) led to a conversion of the borate anion to the complex [B2O(C6H4O2)(py)4][PrCl5(py)] (1). The use of the ILs [EMIM][Catbox] and [BMIM][Catbox] indicates complete transfer of the oxalate groups to the lanthanide ions in reactions with lanthanide chlorides and nitrates yielding the well-known lanthanide oxalates Ln2(C2O4)3·10H2O (Ln = La, Eu). In contrast, the reaction of anhydrous YCl3 with Li[B(C2O4)2] (lithium bis-oxalatoborate = Li[BOB]) in N,N-dimethylformamide (dmf) results in the formation of [B2O(C2O4)2(dmf)2] (2). Transfer of one oxalate group per boron onto the yttrium ion is revealed by the formation of the one-dimensional coordination polymer ∞1[LiYCl2(C2O4)(dmf)3] (3) as additional product. The products were characterized by single-crystal X-ray diffraction as well as powder X-ray diffraction, IR spectroscopy and elemental analysis.},

@article{C7TC03312E,
  abstract = {Smart optical composite materials suitable for ratiometric sensing applications and harvesting options have been developed. The hybrid materials consist of core/shell particles with Fe3O4/SiO2 as the core and different luminescent lanthanide-containing metal-organic frameworks (MOFs) as the shell. The magnetic properties enable collection of microparticles via an external magnetic field and{,} thus{,} a strong signal augmentation of the luminescence signal. Thereby{,} MOF luminescence functions as a read-out signal of the sensing that can be influenced by different chemical compounds{,} e.g. by quenching with low concentrations of water. The combination of MOFs{,} which contain different luminescence centers combined with a different sensitivity towards water{,} results in a system that can be exploited as a ratiometric sensor. We have utilized the MOFs 3[infinity][Eu2(BDC)3][middle dot]2H2O[middle dot]2DMF (BDC2- = benzene dicarboxylate) and 2[infinity][Ln2Cl6(bipy)3][middle dot]2bipy (Ln = Eu{,} Tb; bipy = 4{,}4[prime or minute]-bipyridine) for functionalization of the microparticles{,} resulting in a color-tuned yellow-emitting mixed-MOF composite system together with a Fe3O4/SiO2 core. Interaction with water decreases the luminescence unequally for both luminescence centers{,} which enables a quantitative determination of the water content by analysis of the ratio of the Tb3+ and Eu3+ luminescence bands. This process is supported by possible harvesting via superparamagnetism of the composite. Altogether{,} high sensitivity with a detection limit of 0.3% (20 [small mu ]g) is achieved{,} equal to Karl-Fischer titration but also suitable for an {"}on-the-fly{"} analysis.},
