| 摘 要： | 合成了N-(3,5-二硝基)苯甲酰基-N-叔丁基氮氧自由基(t-BBNO),研究其电子自旋共振(ESR)谱特征与分子结构的关系及溶剂效应,发现与已报道的氮氧自由基的ESR_aN值随溶剂极性增大而变化不同,t-BBNO自由基的ESR_aN值几乎不随溶剂极性不同而变化,说明溶剂效应与溶质分子的电子结构特点密切相关。

| Abstract: | N-(3.5-dinitro)-benzoyl-N-tert-butyl nitroxide(t-BBNO) has been synthesized. According to the data obtained from the spectra of electronic spin resonance(ESR),its molecular structure and the solvent effect are studied . It is found that, being different from the other nitroxides, the ESR's aN value of t-BBNO free radical hardly changes with the polarity of solvents, which shows that the solvent effect has close something to do with the molecular structure of solute. |
