摘要
利用FTIR光谱研究了一种手性液晶化合物 (M1)LB膜的结构与取向 ,该化合物可以形成稳定的单层与多层膜。手性分子中 ,芳香环平面部分倾向于垂直基片表面 ,分子中的烷基链部分则与基底表面法线方向成一定的角度。
The LB films of chiral LCs M 1 were investigated by FTIR transmission and reflection absorption spectra.CaF 2 and vacuum deposition gold plate were used as solid substrate.The LB films can be transferred onto the solid substrate successfully.The orientation of LB films was analysis by comparing the FTIR transmission and reflection absorbance spectroscopy.The aromatic cores part which including the C—O bond was almost perpendicular the substrate surface,the alkyl chain and C=O part has a certain angle titled onto the substrate.
