  Liquid-Phase Syntheses and Material Properties of Two-Dimensional Nanocrystals of Rare Earth–Selenium Compound Containing Planar Se Layers: RESe₂ Nanosheets and RE₄O₄Se₃ Nanoplates

  摘要：

  Synthesis of diverse two-dimensional nanostructures with unique material properties is of current interest and multidisciplinary importance but remains a challenge for trivalent rare earth (RE)-selenium (Se) compounds because of the weak affinity between hard rare earth cations and soft selenium anions. In this article, for the first time, we report a mild solution approach toward a series of two-dimensional trivalent RE-selenium compounds nanocrystals, namely RESe2 nanosheets (RE = La to Nd, for EuSe2, nanobars were obtained) and RE4O4Se3 nanoplates (RE = Nd, Sm, Gd to Ho), under a high chemical potential of selenium obtained by activating SeO2 powder with oleylamine in high boiling point organic solvents. Both kinds of nanocrystals contain Se with -1 valence in planer Se layers, allowing for a great variability in their crystal structures. Satellite diffraction peaks were observed in the electron diffraction pattern of LaSe2 nanosheets, indicating the presence of Peierls distortion in the Se layers. In the RE4O4Se3 nanoplates, the interaction between Se2- ions and [Se-Se](2-) dumbbells in the Se layers increases when the radii of the RE3+ ions decrease along the lanthanide series, resulting in a narrower optical band gap (from 1.96 to 1.73 eV). The LaSe2 nanosheet films fabricated by drop-casting exhibited good electrical conductivity at room temperature (about 1 Omega.cm(-1)). Further, the RE4O4Se3 nanoplates showed very high light extinction capacity in the visible region (extinction coefficient mu(1); 4.4 x 10(5) cm(-1) for Nd4O4Se3, and 3.1 x 10(5) cm(-1) for Gd4O4Se3), comparable to that (5 x 10(5) cm(-1)) of CuInS2 commonly used in solar cells.

  Synthesis of yttrium, lanthanum, neodymium, praseodymium, and lutetium alkoxides and acetylacetonates

  摘要：

  A convenient and practical method is proposed for the synthesis of lanthanide and yttrium alkoxides. The method involves dissolving the metals or their hydrides in a solution of dry HCl in the corresponding alcohol, with subsequent dehalogenation of the LnCl3 solution by an equivalent amount of alkali metal (Na, Li), The rare-earth alkoxides are easily converted into acetylacetonates Ln(acac)3 by the action of acetylacetone.

  lanthanoid Ln(III) complexes was investigated in Me2SO including n-Bu4N(acac) and n-Bu4N(dibm) as ligands (where acac is the acetylacetonate anion and dibm is the diisobutrylmethanate anion). Reversible one electron reduction waves corresponding to Ln(III) complexes→Ln(II) complexes were observed in the concentration range of 5–20 mM of the ligands, including 1 mM lanthanoid perchlorates and 0.1 M TEAP

  An effective one-step approach for the preparation of (porphyrinato)(phthalocyaninato) early lanthanides of type [Br4TPP]Ln[(15C5)4Pc]Ln[Br4TPP], where Br4TPP = 5,10,15,20-tetrakis-(4-bromophenyl)-porphyrinato-ligand, (15C5)4Pc = tetrakis-(15-crown-5)-phthalocyaninato-ligand and Ln = La, Pr, Nd or Eu, is developed. The influence of various factors on the reaction pathway and yields of the complexes is investigated in detail. The developed protocol is found to be general for the early lanthanide subgroup. Variation of the synthetic conditions allowed the determination and isolation of possible side-products, namely heteroleptic double-deckers [Br4TPP]Ln[(15C5)4Pc] (Ln = Nd, Eu) and triple-decker [Br4TPP]Nd[(15C5)4Pc]Nd[(15C5)4Pc]. The peculiarities of the NMR lanthanide-induced shifts (LIS) of resonances of the synthesized triple-decker complexes are precisely investigated. The isostructurality of the synthesized complexes within the series as well as isostructurality with previously synthesized compounds is demonstrated in terms of two-nuclei analysis of LIS.

  The triple-decker complexes of symmetrical type [m Br ₄ TPP ] Ln [(15 C 5)₄ Pc ] Ln [m Br ₄ TPP ] ( Ln -m TD ; Ln = La , Nd ; [(15 C 5)₄ Pc ] = tetra-(15-crown-5)-phthalocyaninato-ligand; [m Br ₄ TPP ] = tetrakis-meso-(3-bromophenyl)-porphyrinato-ligand) are synthesized for the first time with 43% and 36% yield. The applicability of the previously developed selective one-step synthetic approach for the preparation of the mentioned complexes is demonstrated and the limitations, determined by meta-substitution of meso-aryl-fragments, are revealed. The spectral features of the obtained complexes is determined by means of UV-vis and NMR spectroscopy. The hindered rotation of porphyrin meso-substituents in the obtained complexes and formation of statistical set of atropisomers are demonstrated.
