  Kinetic study of ligand release promoted by ammonium ion on bis(N-alkylsalicylaldiminato)zinc(II) complexes in aprotic solvent

  摘要：

  The reaction between ammonium ion and bis(N-alkylsalicylaldiminato)zinc(II) complexes [Zn(R-sal)(2)] (R-sal = anion of N-alkylsalicylaldimine; R = H, n-Bu = n-butyl, t-Bu = tert-butyl, i-Pr = iso-propyl, Et = ethyl) in dry acetonitrile, leads to the release of the ligand. The reaction was studied kinetically at different temperatures and an analysis by mean of a multi-wavelength stopped-flow technique evidences a first-order kinetic as a general rule, and a two exponential profile for the t-butyl substituted complex for the release of one of the bidentate ligands of the Zn(II) complexes. Kinetic and H-1 NMR data indicate that the first step of the release reaction of the ligand is the O-Zn bond breaking. (C) 2000 Elsevier Science S.A. All rights reserved.

  Tribochemically active chelate complexes of salicylideneimines

  摘要：

  N-Alkylsalicylideneimines and their complexes with 3d metals were obtained by chemical (from metal salts) and electrochemical methods (from metals in the zero oxidation state). The compounds obtained were characterized by IR and H-1 NMR spectroscopy and X-ray diffraction analysis. According to crystallographic data, nickel bis(chelate) exists in the trans-planar configuration. A friction test revealed that the tribotechnical characteristics of lubricating formulations are substantially enhanced in the presence of N-alkylsalicylideneiminates.

  A series of novel Zn(II) Schiff base complexes with diphenylamino and carbazole groups that exhibited aggregation-induced emission enhancement were designed and synthesized. The properties of four complexes were investigated by UV–Vis absorption and fluorescence emission spectroscopy, cyclic voltammetry and density functional theory calculations. The fluorescence intensities of the four dyes are weak

  设计并合成了一系列具有二苯基氨基和咔唑基团的新型Zn（II）Schiff碱配合物，这些配合物表现出聚集诱导的发射增强作用。通过紫外可见吸收和荧光发射光谱，循环伏安法和密度泛函理论计算研究了四种配合物的性质。四种染料的荧光强度在四氢呋喃中较弱，但在水/四氢呋喃的混合物中会变强（v / v = 9/1）。这项工作构成了Zn（II）Schiff碱配合物对该现象的首次观察。为了确定AIEE的机理，准备了一个简单的模型复合物，没有可能发生分子内旋转运动。通过仔细分析新配合物之间分子结构和光物理性质的差异，将当前聚集诱导的发射增强归因于固体中受限的分子内旋转运动。
