Facile electrochemical generation of polyoxyethyl-vinylogous tetrathiafulvalene films
Résumé
Electropolymerization of substituted dithiafulvenes is a convenient way to produce conjugated TTF electroactive films. When flexible polyoxyethyl chains link a conjugated TTF, the properties of the electroactive units in the film are the same as those observed in solution. This is illustrated with the existence of molecular movements in the TTF core that were previously described in solution and are clearly detected in the film. With this linker, morphologic investigations performed by in situ EC-AFM show a regular film formation leading to a continuous deposit with no special structures
