摘要
合成了两种芘衍生物,配制了其浓度为10-4mol/L的溶液.采用Z-扫描技术测试了样品溶液在波长为1064 nm,脉宽为20 ps条件下的非线性光学特性.结果表明,1,3,6,8-四(三甲基硅乙炔)芘(1)显示出了较强的非线性折射响应.这主要是由于取代基种类的不同造成的.
Two novel pyrene derivatives were synthesized. The third-order nonlinear optical properties of them were investigated by Z-scan technique with 20 ps pulse width at 1064 nm in CHC13 and THF solution, respectively. Compound 1 showed enhanced nonlinear optical refractive effects compared with 2 and pyrene.
