Copper phthalocyanine-Fe2O3 nanoparticles alternating thin films were fabricated by Langmuir-Blodgett technique. Molecular orientation of [4-(4'-benzyloxy phenyl sulfonyl)phenoxy]-tris-4-(2,4-di-t-phenoxy) phthalocyanine copper (II) in its alternating LB films, deposited at different conditions, was studied by polarized UV-Vis spectra. The tilt extent of the copper phthalocyanine molecule on its LB films increases with the surface pressure of the subphase increasing on the same subphase, or with Fe2O3 concentration decreasing at the same pressure. The orientation of the copper phthalocyanine derivative is important for the gas-sensing properties. The bigger the tilt extent of the phthalocyanine molecule is, the greater the sensitivity of the film is.
采用朗缪尔-布洛杰特技术制备了铜酞菁-Fe2O3纳米颗粒交替薄膜。通过偏振紫外-可见光谱研究了[4-(4'-苄氧基苯基磺酰基)苯氧基]-三-4-(2,4-二叔丁基苯氧基)酞菁铜(II)在不同条件下沉积的交替LB薄膜中的分子取向。在相同亚相上，铜酞菁分子在其LB薄膜上的倾斜程度随亚相表面压力的增加而增加，或者在相同压力下随Fe2O3浓度的降低而增加。铜酞菁衍生物的取向对气敏性能很重要。酞菁分子的倾斜程度越大，薄膜的灵敏度越高。
