本文用粘度、可见光谱和电子自旋共振(ESR)波谱技术研究离子强度和乙醇含量对溴乙烷部分季胺盐化聚-4乙烯基吡啶(EBQP_4VP)-C_u(Ⅱ)络合物在水溶液中的配位结构的影响。高分子-C_u(Ⅱ)络合物离子强度和乙醇含量的变化导致高分子配体链构象的变化,同时引起高分子-C_u(Ⅱ)络合物配位球结构的变化。因而,高分子-C_u(Ⅱ)络合物四方对称结构发生畸变,致使催化氢醌的氧化活性相应变化。
In this paper, the ionic strength and ethanol content were studied by means of viscosity, visible spectrum and electron spin resonance (ESR) spectroscopy. The effect of partial ionization of ethylbromide partially quaternized poly (4-vinylpyridine) (EBQP_4VP) -C_u (Ⅱ) In the coordination structure. The changes of the ionic strength and ethanol content of the polymer-C_u (Ⅱ) complex lead to the change of the conformation of the polymer ligand chain and the change of the coordination sphere structure of the polymer-C_u (Ⅱ) complex. Therefore, the tetragonal structure of polymer C_u (Ⅱ) is distorted, resulting in a corresponding change in the catalytic activity of hydroquinone.
