用高时间分辨电子自旋共振 (TRESR)波谱仪 ,研究了微复相体系中光解二苯甲酮羰自由基的化学诱导动态电子自旋极化 (CIDEP) .实验结果指出 ,在十二醇聚氧乙烯醚 (AEO9) /异丙醇 /水 /辛烷体系的溶致液晶中 ,观察到光解二苯甲酮羰自由基 (Ph2 COH)表现出自旋相关自由基对极化 (SCRP) .在微乳液中 ,则表现出常规的RPM的极化谱 .还从自由基所处微环境性质出发 ,讨论了SCRP的形成机理和有关的物理学性质 .
The chemical-induced dynamic electron spin polarization (CIDEP) of photolysis benzophenone carbonyl free radicals in the micro-multiphase system was investigated by high-resolution electron spin resonance (TRESR) spectroscopy. The experimental results show that in the twelve (Ph2 COH) was observed to exhibit spin-dependent free radical versus polarization (AEO9) / isopropanol / water / octane systems SCRP) .In the microemulsion, the polarization spectrum of conventional RPM was shown. The formation mechanism and related physical properties of SCRP were also discussed based on the microenvironmental properties of the free radical.
