7-羟基喹啉在固态介质中光反应的光谱特性

Photoconversion of 7-hydroxyquinoline in Polymeric Matrix

本文通过观测 7HQ在固态基质中的吸收光谱 ,研究 7HQ被紫外光照射后物种的变化。表明光照前分子主要以烯醇构型存在。受紫外光 337 1nm照射后部分烯醇构型转变为酮式构型和其它构型。样品被光照后存放 2个月 ,其吸收光谱仍保持不变。这些结果说明 7HQ在光存储方面有潜在的应用前景。

In this paper, the absorption spectra of 7HQ in polymeric matrix before and after irradiation with ultraviolet light are observed to study on the conversion of the species of the molecules. The absorption spectra of the sample before irradiation show that the molecules are predominantly enol species and the absorption spectra of the sample irradiated show that some of enol species convert into keto, tautomers and other species. The sample irradiated with ultraviolet light holds for two months can keep its absorption spectra unchanged. This result shows that 7HQ shall have practical application for optical storage.
