摘要
本文以LB膜技术研究了向列相液晶的取向机理.选择了四种不同金属的可溶性酞菁化合物MPc-R_4作为取向材料,拉制成LB膜,诱导向列相正性液晶E-7.通过对菁酞LB膜的表征和液晶取向及电光性能的研究,认为液晶的取向是由分子间的相互作用力决定的.
In this paper,the LB film technique was employed to the investigation on the alignmemt mechanism of nematic liquid crystal. Four kinds of soluble metalic phthalocyanine compounds Langmuir-Boldgett (LB) film were selected as an orienting material to induce the nematic liquid crystal E-7. Through the research on the characterization of phthalocyanine LB films and liquid crystal alignment as well as the electric light property, it is considered that the alignment of liquid crystal is controlled by the imterative force between the molecules.
