Polyoxometalate Monolayers in Langmuir-Blodgett Films
2005
Langmuir and Langmuir-Blodgett (LB) films of a variety of polyoxometalates of different shapes, sizes, and charges were prepared by taking advantage of the adsorption properties of these polyanions on a positively charged monolayer of an organic surfactant spread on water. Three different aspects were investigated. 1) The electrochemical and electrochromic properties of LB films containing the easily reducible polyoxoanion [P2Mo18O62]6-. Absorbance changes of these LB films deposited onto an ITO substrate have been induced by repeated switching of the applied potential. These changes are due to the formation of the colored reduced forms of the polyanion. Coloration and bleaching of the LB f…
Langmuir-Blodgett films based on Prussian Blue derivatives: Towards new hybrid magnetic materials
1999
Abstract The adsorption of dissolved Prussian Blue derivatives along a positively charged monolayer leads to new Langmuir-Blodgett (LB) films presenting a ferromagnetic state at low temperature. Such organic/inorganic systems containing inorganic sheets between organic amphiphilic layers constitute a new series of magnetic lamellar materials.
