| 摘 要： | 用光学线性和非线性方法研究了Ｙ型半花菁／花生酸交替ＬＢ多层膜的光致光学各向异性。在纳秒紫外偏振脉冲激光照射下，ＬＢ多层膜中半花菁分子发色团长轴向紫外光偏振方向重新取向。加热可以使ＬＢ多层膜平面内各向异性消失及Ｈ－聚集体分解。

| Abstract: | Photoinduced optical anisotropy in Y type interleaving hemicyanine/arachidic acid Langmuir Blodgett multilayers has been investigated by optical linear and nonlinear measurements. Under illumination of a polarized UV nanosecond laser beam, the hemicyanine molecules would reorient and align their chromophore axes along the direction of the UV beam polarization. Thermal isotropic process was accompanied by dissociation of the H aggregate in the hemicyanine LB multilayers. |
