  Deciphering Three Beneficial Effects of 2,2′-Bipyridine-N,N′-Dioxide on the Luminescence Sensitization of Lanthanide(III) Hexafluoroacetylacetonate Ternary Complexes

  摘要：

  Lanthanide hexafluoroacetylacetonate ternary complexes with 2,2'-bipyridine-N,N'-dioxide, [Ln(hfa)(3)(bpyO2)], were synthesized for Ln = Eu, Gd, Tb, and Lu and fully characterized by elemental, thermal, and mass-spectrometric analyses. The X-ray crystal structure of [Eu(hfa)(3)(bpyO2)] center dot 0.5C(6)H(6) reveals an octa-coordinate metal ion lying in a severely distorted trigonal dodecahedron geometry; the Eu-O distances lie in the range 2.36-2.44 angstrom with no significant difference between hfa and bpyO2. angstrom detailed comparative photophysical investigation has been carried out to determine the exact influence of the introduction of bpyO2 in the inner coordination sphere of the metal ion in replacement of the two water molecules in [Ln(hfa)(3)(H2O)(2)]center dot While this replacement is detrimental for Tb, it leads to a 15-fold increase in the overall quantum yield for Eu. This large improvement originates from (i) a better sensitization efficiency, the ancillary ligand being responsible for 3/4 of the energy transfer, (ii) elimination of nonradiative deactivation pathways through'harmonics of O-H vibrations, and (iii) reduction in the radiative lifetime. The latter influence is rarely documented, but it accounts here for a approximate to 25% increase in the intrinsic quantum yield, so that more attention should be given to this parameter when designing highly luminescent lanthanide complexes.

  The reaction of hydrated lanthanide hexafluoroacetylacetonates, [Ln(hfa)(3)(H2O)(2)], with 1,4-disubstituted benzenes afforded a new series of one-dimensional coordination polymers [Ln(hfa)(3)(Q)](infinity), where Ln = Eu, Gd, Tb, and Lu and Q = 1,4-diacetylbenzene (acbz), 1,4-diacetoxybenzene (acetbz), or 1,4-dimethyltherephtalate (dmtph). X-ray single crystal analyses reveal [Ln(hfa)(3)(acbz)](infinity) (Ln = Eu, Gd, Tb) consisting of zigzag polymeric chains with Ln Ln Ln angles equal to 128 degrees, while the arrays are more linear in [Eu(hfa)(3)(acetbz)infinity and [Eu(hfa)(3)(dmtph)](infinity), with Ln Ln Ln angles of 165 degrees and 180 degrees, respectively. In all structures, Ln(III) ions are 8-coordinate and lie in distorted square-antiprismatic environments. The coordination polymers are thermally stable up to 180-210 degrees C under a nitrogen atmosphere. Their volatility has been tested in vacuum sublimation experiments at 200-250 degrees C and 10(-2) Torr: the metal organic frameworks with acetbz and dmtph can be quantitatively sublimed, while [Ln(hfa)(3)(acbz)](infinity) undergoes thermal decomposition. The triplet state energies of the ancillary ligands, 21 600 (acetbz), 22 840 (acbz), and 24 500 (dmtph) cm(-1), lie in an ideal range for sensitizing the luminescence of Eu-III and/or Tb-III. As a result, all of the [Ln(hfa)(3)(Q)](infinity) polymers display bright red or green luminescence due to the characteristic D-5(0)-> F-7(J)(J=0-4) or D-5(4) -> F-7(J) (J=6-0) transitions, respectively. Absolute quantum yields reach 51(Eu) and 56(Tb) % for the frameworks built from dmtph. Thin films of [Eu(hfa)(3)(Q)](infinity) with 100-170 nm thickness can be obtained by thermal evaporation (P<3 x 10(-5) Torr, 200-250 degrees C). They are stable over a long period of time, and their photophysical parameters are similar to those of the bulk samples so that their use as active materials in luminescent devices can be envisaged. Mixtures of [Ln(hfa)(3)(dmpth)](infinity) with Ln = Eu and Tb yield color-tunable microcrystalline materials from red to green. Finally, the crystalline samples exhibit strong triboluminescence, which could be useful in the design of pressure and/or damage detection probes.

  An extensive series of tetranuclear Cu(2)(II)Ln(2)(III) complexes [Cu(II)LLn(III)(hfac)(2)](2) (with Ln(III) being all lanthanide(III) ions except for the radioactive Pm-III) has been prepared in order to investigate the nature of the Cu-II-Ln(III) magnetic interactions and to try to answer the following question: What makes the (Cu2Tb2III)-Tb-II and (Cu2Dy2III)-Dy-II complexes single molecule magnets while the other complexes are not? All the complexes within this series possess a similar cyclic tetranuclear structure, in which the Cu-II and Ln(III) ions are arrayed alternately via bridges of ligand complex ((CuL)-L-II). Regular SQUID magnetometry measurements have been performed on the series. The temperature-dependent magnetic susceptibilities from 2 to 300 K and the field-dependent magnetizations from 0 to 5 T at 2 K have been measured for the Cu(2)(II)Ln(2)(III) and Ni(2)(II)Ln(2)(III) complexes, with the Ni(2)(II)Ln(2)(III) complex containing diamagnetic Ni-II ions being used as a reference for the evaluation of the Cu-II-Ln(III) magnetic interactions. These measurements have revealed that the interactions between Cu-II and Ln(III) ions are very weakly antiferromagnetic if Ln = Ce, Nd, Sm, Yb, ferromagnetic if Ln = Gd, Tb, Dy, Ho, Er, Tm, and negligible if Ln = La, Eu, Pr, Lu. With the same goal of better understanding the evolution of the intramolecular magnetic interactions, X-ray magnetic circular dichroism (XMCD) has also been measured on (Cu2Tb2III)-Tb-II, (Cu2Dy2III)-Dy-II, and (Ni2Tb2III)-Tb-II complexes, either at the L- and M-edges of the metal ions or at the K-edge of the N and O atoms. Last, the (Cu2Tb2III)-Tb-II complex exhibiting SMM behavior has received a closer examination of its low temperature magnetic properties down to 0.1 K. These particular measurements have revealed the unusual very slow setting-up of a 3D order below 0.6 K.
