| 摘 要： | 用化学诱导动态核极化（CIDNP）方法研究了三乙胺与2-氯-5-甲氧基对苯醌在 C6D6，CH3CN溶剂中的反应机理，实验结果表明反应过程中首先形成基态电荷转移 络合物（CTC），在CD3CN中，光照电荷分离形成离子自由基对，使三乙胺亚甲基产 生发射极化信号。同时用UV-vis实验证实CTC的存在。

| Abstract: | The mechanisms for the reaction of triethylamine with 2 chloro 5 methoxy p benzoquinone in different solvents under UV irradiation were investigated by the chemically induced dynamic nuclear polarization (CIDNP). The results showed that the charge transfer complex (CTC) was first formed and then charge separation occurred to produce ion radical pairs. The back electron transfer caused the methylene of triethylamine to give emission CIDNP polarization. The UV vis experiment confirmed the existence of CTC as well. |
