偶氮苯光致异构化对紫精-曙红络合的调控

The Photoisomerization of Azobenzene for Regulating the Complex Behavior of Viologen with Eosin

报导了α，ω-偶氮苯、紫精双发色团化合物的合成与性质研究．结果表明偶氮苯的光致顺反异构化可以调控与之相连的紫精与曙红的络合行为，其作用程度的强弱与连接两者的亚甲基链的长度有关．借助1HNMR,通过对构象进行分析解释了上述的研究结果．

In this paper, the synthesis of α, ω-azobenzen, viologen bichromophore long chain compounds, and the study on their photochemical and photophysical properties have been reported. The results indicated that the photoisomerization of azobenzene could regulat the constant of complexation between the viologen and eosin, and the photoregulating effect is correlated strongly with the length of the polymethylene spacer between two chromophores. Based on the spectra data of 1H NMR, the conformation effect has also been discussed and explained preliminarily.
