N-bis(2-(2-methoxyethoxy)ethyl)amino]styryl]-N-methylpyridinium tetraphenylborate, was designed, synthesized and fully characterized. Third-order nonlinear optical properties for the new stilbazolium salt have been explored. The results show that the novel dye possesses very large values of the real part of the cubic hyperpolarizability χ(3), up to 10−12 esu, and displays maximum two-photon absorption cross
一种新颖的唑鎓盐与柔性链,反式- [4- [ N,N- -双(2-(2-甲氧基乙氧基)乙基)氨基]苯乙烯基] - Ñ -methylpyridinium四苯基硼酸,被设计,合成和完全表征。研究了新的stilbazolium盐的三阶非线性光学性质。结果表明,该新型染料具有非常大的立方超极化率χ (3)实部值,最高可达10 -12 esu,并且在950至960 nm的窄波长范围内显示出最大的两个光子吸收截面,但超出范围却显示出很大的χ (3)实部分别由双光子诱导的荧光和使用飞秒脉冲激光在近红外范围内的开/关孔径Z扫描测量确定。
