[structure: see text]. The synthesis and nonlinear optical characterization of two novel heteroaromatic-based chromophores is described. The new dyes present an A-pi-D-pi-A general framework, where A is a pi-deficient heteroaromatic ring (pyridine, quinoline, benzothiazole) and D a pi-excessive pyrrolyl moiety. Both systems exhibit largetwo-photonabsorption (TPA) values in the femtoseconds regime
[结构:见文字]。描述了两种新颖的基于杂芳族化合物的生色团的合成和非线性光学表征。新的染料具有A-pi-D-pi-A的一般结构,其中A是pi缺陷的杂芳族环(吡啶,喹啉,苯并噻唑),D则是pi过量的吡咯基部分。两种系统在飞秒状态下均显示出较大的双光子吸收(TPA)值(TPA横截面在150 fs激光脉冲的作用下高达150 x 10(-50)cm(4)s光子(-1)分子(-1) )。还显示了它们基于TPA的光学限制活性。
