Formation and Features of Skeletonized Structures in Two-Component Langmuir-Blodgett Films

The formation conditions and structural and physical properties of Langmuir-Blodgett (LB) films of a 1,3-diketone: 5-[[1,3-dioxo3-[4-(1-oxooctadecyl)phenyl]propyl]amino]-1,3-benzenedicarboxylic acid (DA) have been studied. The formation and structural features of mono- and multilayer LB films of two-component mixtures of DA and lipid molecules (cetyl alcohol or cetylamine) were characterized by surface pressure-area isotherms, quartz crystal microbalance, surface acoustic wave, ellipsometry, and scanning electron microscopy methods. It has been demonstrated that two-component films made from equimolar mixtures of cobalt 1,3-diketonate and cetylamine have high density and reveal elastic properties as a result of highly ordered structure.
