  Lanthanide phenolates with heterocyclic substituents. Synthesis, structure and luminescent properties

  摘要：

  The complexes of trivalent lanthanides Ce, Sm, Eu, Gd, Tb, Dy with 2-(2-benzoxyazol-2-yl)phenolate (OON), 2-(2-benzothiazol-2-yl)phenolate) (SON) and 2-(2-benzoimidazol-2-yl)phenolate (NON) ligands were synthesized by the reactions of silylamides Ln[N(SiMe3)(2)](3) with respective phenol. Heteroleptic complex Tb(NON)(2)(SON) was obtained when Tb[N(SiMe3)(2)](3) was treated simultaneously with NONH and SONH. X-ray analysis of Ce(OON)(3), Eu(OON)(3), Sm(SON)(3), Gd(NON)(3), Dy(NON)(3) and Tb(NON)(2)(SON) revealed that all the compounds are dimers with two bridging and four terminal XON ligands (XON)(2)Ln(mu-XON)(2)Ln(XON)(2). In the heteroleptic complex the SON ligands are bridging but the NON groups are terminal. The molecules of the complexes in crystals are stacked with short intra- and intermolecular distances between planar ligands. This feature is reflected in the luminescence spectra of Gd, Tb (with SON ligands) and Dy complexes. Photo- and electroluminescence spectra of Ce, Gd and Dy derivatives showed only ligands emission in the region from 430 to 530 nm. The spectra of Sm and Tb complexes contain as well the bands of f-f transitions typical for corresponding metal ion. The complexes of Eu revealed no luminescence. (C) 2012 Elsevier Ltd.

  A lanthanide complex, method of forming and method of using the lanthanide complex as a near-infrared luminescent material are described. The complex includes at least one lanthanide ion and at least one polydentate ligand derived from a molecule having the general formula of Structure 2: where: E represents a heteroatom or heteroatom-containing group and R 1 -R 8 are independently selected from H, —OH, —NH 2 , —SO 3 H, —CO 2 H, halides, optionally substituted organic groups; and conjugated linking groups which link two of the polydentate ligands of Structure 2 together.

  本文介绍了一种镧系络合物，以及形成该络合物的方法和将该络合物用作近红外发光材料的方法。该络合物包括至少一个镧系离子和至少一个聚叶配体，该聚叶配体源自具有结构2的通用公式的分子，其中：E代表杂原子或含杂原子的基团，R1-R8独立选择自H、—OH、—NH2、—SO3H、—CO2H、卤素、可选择取代的有机基团和共轭连接基团，将结构2的两个聚叶配体连接在一起。
