| 摘 要： | 本文以硫代硫酸根离子作为电荷给体(D),系列N-芳基取代马来酰亚胺(RPhMI)作为电荷受体(A),用含水5%的二甲基亚砜(95%DMSO)为溶剂,以紫外可见分光光度法研究了RPhMI与S2O32-作用生成的电荷转移(CT)络合物。以其CT光谱计算了RPhMI的电子亲合能(EA).测定了CT络合物的生成常数K.结果显示,弱的受体N-马来酰亚胺与强的给体硫代硫酸根负离子可以生成稳定的CT络合物。文章还讨论了CT络合物的可能结构及取代基极性与CT络合物的稳定性关系。

| Abstract: | The Charge transfer(CT)complexes formed between N-arylmaleimides(RPhMI)as the acceptors and thiosulfate anion(S2O32-) as donor in 95% DMSO/H2O were studied by UV-Vis spectroscopy.The electron affinities(EA)of RPhMI had been calculated from the CT spectra,And the formation constants(K)of the CT complexes were determined.The results indicate that weak acceptors,N-arylmaleimides could form stable CT complexes with the thiosulfate anion which acts as a strong donor,The possible structure of the CT complexes and the relationship of their stability and the substituent polarlity of RPHMI were discussed. |
