| 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. |
