摘要: 本文测定了用溴乙烷部分季胺盐化聚4-乙烯基吡啶(EBQP4VP)-CU(Ⅱ)络合物的可见光谱和电子自旋共振(ESR)波谱,研究了温度、配位体/Cu(Ⅱ)摩尔比、溶液的pH值和高分子配位体的季胺盐化度(Q)的变化对高分子-Cu(Ⅱ)络合物配位结构的影响。在配位体/Cu(Ⅱ)摩尔比20:1下,随着溶液pH值增大,或是Q值减小,溶液的比浓粘度下降,因而高分子链形态趋于卷曲,催化氢醌的氧化活性增大,此时高分子-CU(Ⅱ)络合物[CuL4](L为高分子配位体)的配位结构呈四方畸变的八面体结构。

Abstract: Visible and electron spin resonance spectra of the copper (I) comple of partially quaternized poly(4-vinylpyridine) by ethyl bromide(EBQP4VP) by ethyl bromide(EBQP4VP) were measured. Effects of varying temperature, Iigand/Cu(J) mole ratio, pH value of solution and the percentage of quater-nization(Q) of polymer ligand on the coordination structure of polymer-Cu (I) complex were investigated. At ligand/Cu (Ⅱ) mole ratio 2011, the reduced viscosities of solution decrease with increasing pH value of solution or decreasing Q value. Hence the shape of the polymer chain is markedly crimple, the oxidation activity of catalytic hydroquinone increases. In this time the coordination of polymer-Cu(Ⅱ) complex[CuL4] (L is polymer ligand) is a tetragonally distorted octahedral structure.
