Abstract
A series of amphiphilic complexes of N-octadecyl-8-hydroxy-2-quinoline carboxamide, M(HO)2 (M=Mg, Ca, Mn, Ni, Zn, Pb), form a stable monolayer on a pure water subphase and can be easily fabricated as fairly stable uniform LB films. Absorption spectra and low-angle X-ray diffraction measurements showed that these LB films had good homogeneity and were Y-type bilayer films. From the position of the Bragg peaks, a thickness of ca. 5.38∼5.63 nm per bilayer were obtained. X-ray photoelectron spectroscopy analysis reveals a M : C : N ratio in the LB films consistent with the M(HO)2 on stoichiometry. These LB films exhibit intense fluorescence and may be used as emitting material of electroluminescent devices.
