摘要
设计合成及表征了一系列含有不同取代基的芳香族偶氮化合物。通过简并四波混频方法(DFWM)测试了它们的三阶非线性光学特性,并考察了取代基电子效应对芳香族偶氮化合物三阶非线性光学性能及荧光性能的影响。它们的三阶非线性极化系数关系为:BGA-AZON>BGA-AZOB>BGA-AZOO。用相同的激发光激发它们得到的荧光发射光谱的强度关系为:BGA-AZON<BGA-AZOB<BGA-AZOO。
A series of azobenzenes with different electronic effect substituents were synthesized and characterized. The third-order nonlinear optical characteristics of the azobenzenes were studied by DFWM. The effects of electronic effect of the different substituents on the third-order NLO coefficient and the fluorescence behavior of the azobenzenes were investigated. The order of the third-order NLO coefficients of the azobenzenes is：BGA-AZON 〉 BGA-AZOB 〉 BGA-AZOO. The order of the intensities of the azobenzenes is ： BGA-AZON 〈 BGA-AZOB 〈 BGA-AZOO.
