通过Langmuir Blodgett技术制备了酞菁铜 氧化铁纳米粒子交替LB膜 ,利用偏振紫外 可见光谱对酞菁铜衍生物在不同制膜条件下所制得的交替膜中的分子取向进行了研究。结果表明 ,在同一氧化铁溶胶亚相中 ,随着表面压的增大 ,或在相同的表面压下 ,随着亚相中氧化铁浓度的减小 ,酞菁铜分子在其复合LB膜中倾斜程度变大。 The LB films of copper phthalocyanine iron oxide nanoparticles were prepared by Langmuir Blodgett technique. The molecular orientation of the copper phthalocyanine derivatives in the alternate films prepared by different film-forming conditions was studied by polarized UV-visible spectroscopy. The results show that in the same iron oxide sol subphase, with the increase of the surface pressure, or under the same surface pressure, with the reduction of the iron oxide concentration in the subphase, copper phthalocyanine molecules in the composite LB film The degree of tilt becomes larger.
