(Z)-2-(1-(1-(2,4-dimethylphenyl)-3-oxo-3-phenylprop-1-en-2-yl)pyridin-2(1H)ylidene) malononitrile was prepared and structurally analyzed using single-crystal X-ray diffraction. This new compound's quadratic and cubic susceptibilities at 1064 nm were analyzed and evaluated using the second and third harmonic generation methods after deposition in PMMA polymer thin films. These films have been used for
一种新的共轭查尔酮化合物(Z)-2-(1-(1-(2,4-二甲基苯基)-3-氧代-3-苯基丙-1-en-2-基)pyridin-2(1 H制备了亚基)丙二腈,并使用单晶 X 射线衍射进行了结构分析。这种新化合物在 PMMA 聚合物薄膜中沉积后,使用二次和三次谐波发生方法对 1064 nm 处的二次和三次磁化率进行了分析和评估。这些薄膜已用于使用电晕极化技术实现的感应二次谐波产生测量。该化合物的电偶极矩、静态偶极极化率和初始超极化率的补充信息是通过 DFT/B3LYP/6-311G++ (d, p) 和 Gaussian 09 软件进行的密度泛函理论 (DFT) 计算获得的。研究结果表明,与之前已发表的查耳酮 NLO 晶体相比,合成的晶体具有更高的晶体透明度,极化率和 π 共轭。特别地,(Z)-2-(1-(1-(2,4-二甲基苯基)-3-氧代-3-苯基丙-1-烯-2-基)吡啶-2(1H )亚
