| 摘 要： | 测定了9-乙烯基蒽和对-N,N-二甲氨基苯乙烯体系在不同极性的溶剂中的荧光光谱和荧光量子产率。发现随着溶剂极性的增加,激基络合物的荧光发生红移,荧光量子产率降低。同时9-乙烯基蒽和对-N,N-二甲氨基苯乙烯之间的光二聚产物的相对产率也降低。并讨论了经过激基络合物中间体的光二聚反应机理。

| Abstract: | It was found that exciplex can be formed between singlet excited state of 9-vinyl anthracene and p-N, N-dimethylamino styrene in various solvents. Exciplex emission Wavelength red shifts and fluorescence quantum yield Φe of exciplex decrease with the increase of the polarity of solvents. The relative yield of photodimerization reduces with Φe. Exciplex intermediate mechanism was suggested for the photodimerization between 9-vinyl anthracene and p-N, N-dimethylamino styrene. |
