  • Synthesis, structures and characterisations of truly homoleptic acetonitrile Ln3+ complexes in solid state and in solution

    Total halide abstraction from LnCl3 by Ag[Al(OC(CF3)3)4]/CH3CN has been confirmed for a series of lanthanide metal ions by the structural characterization of [Ln(CH3CN)n][Al(OC(CF3)3)4]3 (n=9, Ln3+=Nd, Eu, Gd, Dy; n=8, Ln3+=Tm) complexes. Evidence for the very low coordinating ability of the [Al(OC(CF3)3)4]- anion towards Ln3+ ions is provided in the solid state (X-ray, IR and Raman spectroscopy) and
    通过[Ln(CH3CN)n] [Al(OC(CF3)3]的结构表征,已经证实了一系列镧系元素金属离子通过Ag [Al(OC(CF3)3)4 / CH3CN从LnCl3中提取总卤化物)4] 3(n = 9,Ln3 + = Nd,Eu,Gd,Dy; n = 8,Ln3 + = Tm)络合物。在固态(X射线,IR和拉曼光谱)和无水乙腈溶液(电导率,EPR)中,[Al(OC(CF3)3)4]-阴离子对Ln3 +离子的配位能力非常低的证据。和NMR测量)。在固态均相配位的九配位乙腈物种中,镧系元素是Ln系列的开始(Nd)和中间(Eu,Gd,Dy)的特征,N原子周围的N个供体原子具有单峰方形反棱角排列。金属中心;而对于系列(Tm)末尾的物种,则有八种协调的物种具有正方形反棱角排列的代表。在无水乙腈溶液中,电导率测量显示所有化合物的电解质类型为3:1。EPR和19F NMR谱线加宽测量证明镧系元素络合物
  • A p-tert-butylcalix[4]arene functionalised at its lower rim with ether-amide pendant arms acts as an inorganic–organic receptor: structural and photophysical properties of its lanthanide complexes

    The new narrow-rim functionalised receptor 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetrakis[2-(diethylcarbamoylmethoxy)ethoxy]calix[4]arene (A4bL4) has been synthesised. NMR spectra show it to adopt a cone conformation in solution with a time-averaged C4v symmetry. A4bL4 reacts with trivalent lanthanide ions in acetonitrile to yield 1 ∶ 1 complexes with logK1 in the range 8.6–9.6, as demonstrated by ES-MS, 1H- and 13C-NMR data. Complexes with Ln = Eu, Gd, Tb, and Lu have been isolated and the crystal structure of [Lu(A4bL4)(H2O)](CF3SO3)3·2Et2O shows the metal ion encapsulated in the cavity formed by the four arms. LuIII is 9-co-ordinated, being bound to the four ether and four carbonyl functions and to a water molecule itself H-bonded to the phenolic ether functions, which rigidifies the cavity formed by the pendant arms. Additionally, an ether molecule is inserted into the hydrophobic cavity defined by the aromatic rings. Both NMR (La, Lu) and luminescence (Eu, Tb) data point to a fairly high local symmetry at the metal centre, while lifetime determinations are consistent with the co-ordination of an inner-sphere water molecule. The new ligand sensitises the luminescence of the TbIII ion (Qabs = 5.8% in acetonitrile, τF  = 1.42 ms) while the probable presence of a LMCT state severely limits such a process for EuIII: Qabs = 2.0%, τF  = 0.73 ms.
    新的窄边缘功能化受体5,11,17,23-四叔丁基-25,26,27,28-四[(2-(二乙基氨基甲氧基)乙氧基)]大环[4]芳烃(A4bL4)已成功合成。NMR光谱显示其在溶液中呈现锥体构象,具有时间平均的C4v对称性。A4bL4与丙三价铕、镓、铽、铥离子在乙腈中反应,生成1:1的配合物,logK1范围为8.6-9.6,这通过ES-MS、1H-和13C-NMR数据得到了证实。已分离出Ln = Eu、Gd、Tb和Lu的配合物,且[Lu(A4bL4)(H2O)](CF3SO3)3·2Et2O的晶体结构显示金属离子被四个臂形成的腔体包裹。LuIII为9配位状态,连接四个醚基和四个羰基功能团,以及一个通过氢键与酚醚基团相连的水分子,从而固定了由悬臂形成的腔体。此外,一个醚分子被插入定义为芳香环的疏水腔体中。NMR(La, Lu)和光致发光(Eu, Tb)数据均指向金属中心具有相对较高的局部对称性,而寿命测定与内层水分子的配位一致。新配体使得TbIII离子的发光敏感化(Qabs = 5.8%在乙腈中,τF = 1.42 ms),而LMCT状态的可能存在严重限制了EuIII的这种过程:Qabs = 2.0%,τF = 0.73 ms。

    the phenoxo bridge. It has been possible to obtain complexes with an alternate Cu‐Gd arrangement involving more than two Cu‐Gd entities when two amidato bridges are present. These two amidato bridges may come from a main ligand, as in the case of tetraanionic ligands possessing two amide functions, or from two different ligands involving one amide function that are assembled by a Gd ion through their
    具有内部N 2 O 2,外部O 2 O 2或O 2 O配位点和来自酰胺功能的氧原子(不参与这些位点)的三阴离子配体产生双核Cu-Ln络合物,其自组装为四核物质Cu和Ln离子的另一种排列方式。这种交替的Cu-Gd排列阻碍了可能反铁磁性的Cu-Cu和Gd-Gd相互作用,并有利于铁磁性Cu-Gd相互作用,其强度取决于电桥的性质,由单个氧原子制成的苯氧基桥或所制造的酰胺桥。三个NCO原子。根据不同的配体,苯氧基桥可以是单(CuOGd)或双(CuO 2Gd),而amidato桥始终是单个(CuNCOGd)桥。涉及通过两个amidato桥的三核Cu-Gd-Cu排列的特殊复合物证实,通过amidato桥的Cu-Gd相互作用始终弱于通过phenoxo桥的相互作用。当存在两个酰胺桥时,可以使用涉及两个以上Cu-Gd实体的备用Cu-Gd排列获得配合物。这两个酰胺基桥可以来自主要配体,例如具有两个酰胺官能团的四
