  Synthesis, structure and fluorescent properties of 2-(1H-benzoimidazol-2-yl)quinolin-8-ol ligands and their zinc complexes

  摘要：

  A series of 2-(1H-benzoimidazol-2-yl)quinolin-8-ol ligands (L1-L5) and their Zn(II) complexes (C1-C6) were synthesized and characterized by spectroscopic and elemental analyses. The molecular structures of C1 and C6 were confirmed by single-crystal X-ray diffraction; the zinc centre in complex C1 was found to be five-coordination as a distorted tetrahedral geometry, meanwhile the zinc centre in complex C6 adopted as six-coordination as a octahedral geometry. UV-Vis absorption and fluorescent spectra in different solvent were measured, and the substituent effects as well as those of the solvents on the luminescent properties were analyzed. The maximum emission wavelengths of all complexes were generally blue-shifted compared to the free ligands. (C) 2012 Elsevier B. V. All rights reserved.

  A series of 2-benzoimidazol-8-ethoxyquinolines (L1–L6) and the nickel dihalides thereof (C1–C12) were synthesized and characterized by elemental analysis and infrared spectroscopy. The molecular structures of representative complexes were determined by single crystal X-ray diffraction which revealed a distorted pyramidal geometry at nickel. All complexes, when activated with Et2AlCl, showed high activities towards ethylene oligomerization and enhanced thermodynamic stability.

  本研究合成了一系列 2-苯并咪唑-8-乙氧基喹啉（L1-L6）及其二卤化镍（C1-C12），并通过元素分析和红外光谱进行了表征。通过单晶 X 射线衍射确定了代表性配合物的分子结构，发现镍的几何形状为扭曲的金字塔形。所有配合物在用 Et2AlCl 活化后，都显示出较高的乙烯低聚活性和较强的热力学稳定性。

  [Ln2(L12 b‐2 H)n] (n=2, 3) complexes is further abruptly modulated along the lanthanide series (Ln=La to Lu), which provides an unprecedented tool for 1) tuning the number of ligand strands in the final helicates, 2) selectively coordinating lanthanides in the various complexes, and 3) controlling the ratio of lanthanide‐containing polymers over discrete assemblies.
