均相溶液与微复相体系中光解自由基的CIDEP研究

本文总结了利用自己研制的高时间分辨率电子自旋共振波谱仪，在研究均相溶液与微复相体系中光解自由基的化学诱导动态电子极化（ＣＩＤＥＰ）方面所做的主要工作首先介绍了高时间分辨电子自旋共振波谱仪的原理与结构，然后报道对多种敏化剂分子的ＣＩＤＥＰ研究。在乙二醇均相溶液中，苯醌、蒽醌、萘醌等为三重态极化的中性自由基。在表面活性剂ＴＸ－１００胶束体系中，获得了这些分子的负离子极化自由基。研究了含硫酸溶液中极化的

CIDEP STUDY OF THE PHOTOLIZED RADICALS IN THE HOMOGENEOUS SOLVENTS AND MICROHETERO-GENEOUS PHASE SYSTEMS

By the using the homemade electron spin resonance spectrometer wi th high time resolution, the CIDEP study on the laser photolized radicals in the homogeneous solvents and micro-heterogeneous phase systems were summarized. The principle and the structure of the TR-ESR spectrometer were introduced. The CID EP study on several photosensitive molecules was reported. In the ethylene glyco l homogeneous solution the neutral radicals of the p-benzoquinone, of the 1-4-na pthoquinone or the anthraquinone with TM polarization were appeared, and in the micelle system with the surfactant TX-100 the polarization anion radicals were o btained. The proton exchange of the polarized benzoquinone radical in solution c ontained sulfuric acid was studied. The SCRP mechanism polarization of the photo lyzed benzophenone radical in the / isopropanol / liquid crystal system was obse rved.
