FTIR spectra of langmuir-blodgett films.

Photoacoustic plasmon resonance spectra of Langmuir-Blodgett films

The surface plasmon spectra of Langmuir-Blodgett (LB) films have been investigated by combining photoacoustic technique with resonant attenuated total reflection spectroscopy. By this technique, the experimental PA angular spectra of cadmium stearate LB films have been obtained. According to the electromagnetic theory and considering the anisotropic properties of LB films, as well as based on t...

Langmuir-Blodgett Films of Supported Polyester Dendrimers

Amphiphiles with a dendritic structure are attractive materials as they combine the features of dendrimers with the self-assembling properties and interfacial behavior of water-air affinities. We have synthesized three generations of polyester dendrimers and studied their interfacial properties on the Langmuir films. The behavior obtained was, as a rule, the lowest generation dendrimers behavin...

Stable ordering in Langmuir-Blodgett films.

Defects in the layering of Langmuir-Blodgett (LB) films can be eliminated by depositing from the appropriate monolayer phase at the air-water interface. LB films deposited from the hexagonal phase of cadmium arachidate (CdA2) at pH 7 spontaneously transform into the bulk soap structure, a centrosymmetric bilayer with an orthorhombic herringbone packing. A large wavelength folding mechanism acce...

Photoinduced Electron Transfer in Langmuir-blodgett Films

Photoinduced electron transfer from an excited donor molecule (oxacyanine) to an acceptor molecule (viologen) located at the same interface in monolayer assemblies has been studied by measuring steady state fluorescence quenching and the excited state decay of the donor molecule. Donor and acceptor molecules are incorporated in matrix monolayers of arachidic acid and methyl arachidate, with a m...
