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

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