摘要：

A crown ether liquid crystal, N,N-bis[4-(4-heptoxybenzoyloxy)benzoyl]-1,10-diaza-4,7,13,16-tetraoxacyclooctadecane, is spread on the air-water interface to create monolayers. The surface pressure-area curves show that the phase transition of the monolayers is accompanied by a change of the liquid crystal molecular structure. The features of the monolayers depend on the temperature of the subphase and the interaction between crown ether and metal ions in the subphase. UV-visible spectroscopy and X-ray diffraction show that the transferred Langmuir-Blodgett films have uniform ordered layer structure and the crown ether in Langmuir-Blodgett films can recognize metal ions.
