<br/>Dawson-Wells lacunary structures derivatized with organosilyl hydrocarbon tails previously characterized by electrochemical and spectroelectrochemical methods have been further investigated using the Langmuir-Blodgett technique. The organic/inorganic hybrid molecules displayed tunable redox behavior and electrochromic properties that would also be expected from non-modified polyoxometalates. Inherent amphiphilic properties of these novel compounds allowed for the formation and deposition of an elastic Langmuir-Blodgett monolayer without the use of organic surfactants on the air-water interphase, suggesting additional functionality not seen in ordinary polyoxometalates. In general it was found that these materials possess properties similar to inorganic polyoxometalates, but with added functionality analagous to surfactant encapsulated polyoxometalates.
