| 摘 要： | 随着人们对吸附态有机分子光谱性质的研究的不断深入,光化学中的一个重要方面——表面光化学,也得到了很大的发展。在固体表面上,人们观察到了许多与溶液中不同的现象。这主要是由于固体表面上常常表现出某种特有的吸附特性,从而对被吸附物质的能级状态和分子结构产生影响,进而改变了它们的反应性能,这类报道已有很多1]。

| Abstract: | The 9,10-dicyanoanthracene and rose bengal sensitized photooxygenation of phenyl substituted ethylenes,such as tetraphenylethylene; 1,1-diphenylethylene; trans-stilbene and α,α’-dimethylstilbene,on the surface of silica gel was investigated.Photooxygenation products were characterized using comparation with authentic samples.The product distribution of photooxygenation reaction were measured.These results indicate photooxygenation reaction in these cases proceeds via the singlet oxygen pathway. |

| Keywords: | photosensitized oxidation silica gel surface phenylsubstituted ethylene |
