本文测定了用溴乙烷部分季胺盐化聚4-乙烯基吡啶(EBQP_4VP)-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〔CuL_4〕(L为高分子配位体)的配位结构呈四方畸变的八面体结构。
In this paper, the visible spectra and electron spin resonance (ESR) spectra of the partially quaternized poly (4-vinylpyridine) (EBQP_4VP) -CU (Ⅱ) Effect of Cu (Ⅱ) molar ratio, pH value of solution and quaternary ammonium salinity (Q) on the coordination structure of polymer Cu (Ⅱ) complex. Under the ligand / Cu (Ⅱ) molar ratio of 20: 1, as the pH of the solution increases or the Q value decreases, the reduced viscosity of the solution decreases and the polymer chain tends to curl. The catalytic hydroquinone The coordination structure of the polymer-Cu (II) complex [CuL_4] (L is a polymer ligand) shows a tetragonal octahedral structure.
