To achieve excellent second nonlinearoptical properties, a new series of hybrid films with homogeneous morphology were fabricated via a Diels–Alder reaction of a maleimide modified trichromophore dendrimer with a furan-containing alkoxysilane dye. The hybrid films were cured. The second-order nonlinearoptical behavior of the hybrid films were investigated through second harmonic generation (SHG)
为了获得优异的第二非线性光学性能,通过马来酰亚胺改性的三色团树状大分子与含呋喃的烷氧基硅烷染料的狄尔斯-阿尔德反应制备了一系列具有均一形态的杂化膜。杂化膜被固化。通过在1064 nm的二次谐波产生(SHG)实验研究了杂化薄膜的二阶非线性光学行为。随着生色团含量从16.56 wt%增加到66.56 wt%,SHG系数d 33的共振增强值趋于增强。与聚合物膜相比,杂化膜的d 33被确定为93.51 pm V -1与生色团密度降低约33.44 wt%相比,显示出24.41%的改善。此外,该杂化膜显示出123℃的提高的T d / 2。这种Diels–Alder交联混合膜将成为非线性光学材料和器件开发中的新选择。
