摘要: 研究了含有双臂胆甾基的氮杂冠醚化合物的单分子膜成膜特性,测试了其LB膜的吸收光谱和小角X-射线衍射谱。结果表明,这种化合物成膜性能和转移性能比单臂的胆甾基氮杂冠醚化合物好。结合CPK原子模型,推测了该分子在膜中的取向和构型。

Abstract: Monolayer of diaza-crown ether double-armed with cholesteric units was prepared and the surface pressure area curve showed its good and stable film characterization. The case is altogether diffrent from the experimental results of its monoarm liquid crystalline crown ether. UV absorption spectra and low-angle diffraction pattern of multilayer suggested that monolayer could be easily transferred onto substrates to form well organized layered structure with each layer having the same uniform thickness of 2.6 nm. Relating to CPK atomic model, the molecular configuration in LB films was speculated.
