可聚合推拉型偶氮苯染料分子二阶极化率的测算

Evaluation of the Second Order Molecular Susceptibility of Some Polymerizable Push pull Azobenzene Dyes

用溶致变色的方法测算了合成的可聚合推拉型偶氮苯分子二阶极化率（βＣＴ），讨论了取代基团对βＣＴ的影响。结果表明：可聚合偶氮苯染料具有较大的分子二阶极化率，βＣＴ值１０－２９ｅｓｕ量级。

Some polymerizable push pull azobenzene dyes were prepared and the values of their second order molecular susceptibility, β CT , were determined by solvatochromism technique. The values of β CT were in the order of (1.0￣35.2)×10 -29 esu. The effect of substituting groups on the azobenzene dyes on β CT was also discussed in the paper.
