摘要: 首次研究了4种单臂液晶冠醚(1~4)的LB膜成膜特性,实验发现它们在气-液界面均可形成单分子膜,但4的稳定性较差,3易转移到玻璃基片上形成Y型膜。4种化合物与硬脂酸以1:1混合形成稳定的Y型LB膜。小角X射线衍射证实了膜的有序结构。用CPK原子模型对成膜分子构型和面积进行了估算,其结果与实验一致,并讨论了分子结构对成膜性能的影响。

关键词: LB膜, 液晶冠醚, CPK原子模型

Abstract: Four monoarm liquid crystalline crown ethers(1-4) were first studied by the method of LBtechnique.Among them, 1, 2 and 3 were found to form stable monolayers at air-water interface but 4 not.Monolayers formed by 3 could easily be transferred onto glass substrate to assemble in and to form Ytype LBfilm, Furthermore, the mixed LBfilms of the four compounds with stearic acid(1:1) were studied and Ytype mixed LBfilms were obtained.All above were characterized by π-Acurves and low angle X-ray diffractions.The molecular configurations in the films were estimated with CPKatomic model which gave the same results as experiments.The effect of molecular structures on the stability of LBfilms was briefly discussed.

Key words: LB film, Liquid crystalline crown ether, CPK atomic model
