项目摘要

In this project, as the advanced investigations of the electron-transfer stopped flow method, we analyzed the reactions of short lived aromatic cation radicals in acetonitrile. For the reactions of anisidine and N-methyl anisidine cation radicals, it was found that the reaction mechanism changed as well as the reactivity. In addition, the electron-transfer stopped-flow method was revealed the effects of the substituents on the meta-and ortho- positions in the reactions of aniline derivative cation radicals and the differences in the reactivity of the dimmer and trimer cation radicals of thiophene derivative. In relation with the former case, systematic investigations were performed for the meta- chloro-, methyl- and methoxy-substituted diphenylamine cation radicals in acetonitrile. As the result, it was clarified from the kinetic view point that there are the two types of the consecutive reactions, i.e., the cation radical-cation radical coupling reaction and to the cyclization reaction of single cation radical depending on the substituents.Furthermore, the electron-transfer stopped flow method was applied to the measurement of the time-resolved visible absorption spectra of the cation radicals and dications of triarylamine derivative molecules, which should give information about the, reactivity and the stability depending on the substituents and molecular structures. Consequently, some bulky substituents were found to affect the reactivities of the di cations significantly. In addition, the electronic optical properties of the oxidized states of amine-based organic high-spin systems were investigated.

在这个项目中，随着电子转移停止流量法的高级研究，我们分析了乙腈中短活芳族阳离子自由基的反应。对于苯胺和N-甲基苯胺阳离子自由基的反应，发现反应机理以及反应性发生了变化。此外，电子转移停止的方法揭示了取代基对苯胺衍生物阳离子自由基反应中元和矫正位置的影响，以及硫烯衍生物的调光和三聚体阳离子自由基的反应性差异。与前一种情况有关，对乙腈中的元氯，甲基和甲氧基取代的二苯胺阳离子自由基进行了系统研究。结果，从动力学角度阐明了连续反应的两种类型，即，阳离子自由基自由基自由基反应以及单个阳离子自由基的环化反应，取决于取代的取决于取代基，将电子 - 转移方法应用于时间范围的范围，并将其测量的范围用于范围的范围。三院衍生物分子的分量，应根据取代因素和分子结构提供有关反应性，反应性和稳定性的信息。因此，发现某些笨重的取代基会显着影响二阳离子的反应性。此外，研究了基于胺的有机高旋转系统的氧化态的电子光学性能。
