The LB films of ten amphiphilic complexes of N-hexadecyl-8-hydroxy-2- quinolinecarboxamide were deposited and their properties and structure were characterized by π -A isotherms and low-angle X-ray diffraction analysis. The molecular areas per complex are (1.25±0.06)nm^2 and (0. 74± 0.06)nm^2, which correspond to the change of the orientation of complex in the monolayer. These LB films are oriented in superlattic structure. The height of the bilayer LB films is about (5.0±0.1)nm. Anisotropy of conductivity was observed in the LB films. The in plane conductivity of these LB films on quartz substrate and the vertical conductivity on ITO glass have been determined to be ca. 10^-^5S.m^- ^1 and 10^-^9S.m^-^1, respectively. These LB films have intense fluorescent emission and were used as the emitter material in the electroluminescent device. The electroluminescent devices with a single layer structure was constructed using LaL~2(H~2O)~4Cl as the emitter material. Green-yellow electroluminescence was observed with brightness of ca. 330 cd/m^2 and a low drive voltage of 9V.
