| 摘 要： | 研究了双（苯并唑）芪的光物理行为和光顺反异构化反应，对这类化合物的发光光谱不依赖于溶剂极性的原因进行了初步讨论．异构化反应中，发现乙二醇引入时会加速该化合物反－顺异构化和抑制顺－反过程的回复，其原因可能是与生成了顺式异构体两个苯基苯并唑间的氢键有关．

| Abstract: | The photophysical behaviors and the photoisomerization reaction of bis(2 benzoxazolyl) stilbene have been studied. The relation of the solvent polarity and the emission spectrum of these compounds were discussed preliminarily. It was found that the introduction of small amount of ethylene glycol in the system, the process of trans cis photoisomerization was improved where the thermo recover process was inhibited evidently. It was proposed that this phenomenon is ascribed to the formation of hydrogen bonds between benzoxazolyl groups and the ethylene glycol. |
