  摘要：

  A novel organic assembly, formed between 3,5-dinitro-4-methylbenzoic acid and trans-1,2-bis(4-pyridyl)ethene under hydrothermal conditions in the presence of Pr(III) and a layered structure obtained by direct co-crystallization of the reactants at ambient conditions is reported. The structures of the complexes were established, unambiguously, by single crystal X-ray diffraction methods. (c) 2005 Elsevier Ltd. All rights reserved.

  A rare earth-based nanoparticle magnetic resonance contrast agent and a preparation method thereof are provided. The rare earth-based nanoparticle magnetic resonance contrast agent is rare earth-based inorganic nanoparticles having the surfaces coated with hydrophilic ligands. The rare earth-based nanoparticles are first obtained by a high-temperature oil phase reaction, and then the surfaces thereof are coated with hydrophilic molecules to obtain the rare earth-based nanoparticle magnetic resonance contrast agent. Compared with the existing clinical contrast agent, the magnetic resonance contrast agent of the present invention has a greatly improved relaxivity, a good imaging effect, a low required injection dose, and long in vivo residence time. In addition, the rigid structure of the inorganic nanoparticles can effectively reduce the leakage possibility of gadolinium ions.

  Three bis[octakis-(2-thienyl)phthalocyaninato] rare-earth metal(III) phthalocyanine complexes (Pc[Formula: see text]Pr, Pc[Formula: see text]Sm, Pc[Formula: see text]Gd) were synthesized for the first time. The new compounds were characterized by UV-vis, NMR, FT-IR, mass spectroscopies as well as elemental analysis and electrochemistry. Production of singlet oxygen was also estimated by 9,10-dimethylanthracene method.

  Oxygen permeation property of A-site partially substituted barium cobaltites, A′xBa1-xCo0.7Fe0.3O3-δ (A′=Ba, Pr, Gd, Dy, Y and Yb), were examined. Substitution of Ba by Dy, Y or Yb was found to stabilize cubic perovskite structure even when x remained as small as 0.05. As a result, oxygen permeation through the disks made of these oxides appeared at temperature lower than 500 °C, and reached fairly

  and the resolved RRR-Λ and SSS-Δ complexes show strong circularly polarized luminescence. The molecular quadratic hyperpolarizability ⟨βHLS⟩ has been measured in solution using hyper-Raleigh light-scattering methods, for the whole series of lanthanide complexes of one ligand. The values of ⟨βHLS⟩ reach a maximum around the center of the series and are not simply dependent on the number of f electrons

  基于含有吡啶基-2-次膦酸酯基团的三氮杂环壬烷的非齿配体与固态和溶液中的 Ln 离子形成同构系列的配合物。Ln 离子有效地与溶剂环境隔离。晶体结构揭示了刚性C 3-对称的三棱柱棱柱配位几何结构，在溶液中保持甲基和苯基次膦酸盐系列，如多核 NMR 分析所示。对钆配合物中水质子弛豫场依赖性的可变温度测量表明，这些系统将溶剂排除在主要配位环境之外，并使第二个溶剂化领域最小化。通过 EPR 和 NMR 方法估计甲基次膦酸钆配合物的电子弛豫时间为 550 (±150) ps，而铽-镱系列的值约为 0.30-0.05 ps，通过分析场依赖性推断 (4.7 –16.5 T) 的31P NMR纵向弛豫时间。将值与类似的氮杂羧酸配体配合物进行比较，支持供体原子极化率在确定电子弛豫中的关键作用。比较了钐、铕、铽和镝配合物溶液中的光谱发射行为，分辨的RRR -Λ和SSS - Δ配合物表现出强圆偏振发光。对于一个
