Abstract

Langmuir-Blodgett films of [Au(tmdt)₂] [tmdt^2- = bis(methylthio)tetrathiafulvalenedithiolate] without alkyl chains are described. We synthesized tridecylmethylammonium salt of complex 1 as a film forming material so that the alkyl chains of the salt make the complex soluble in solution and help the formation of monolayers. The complex 1 formed stable monolayers at the air-water interface, which were successfully transferred to solid substrates by the horizontal lifting method. The oxidation of the complex to the neutral form occurred during the film forming process, which was indicated by the IR measurements. The alkylammonium part was removed by methanol and the single component LB films of neutral [Au(tmdt)₂] were obtained. The LB films showed semiconducting behavior after electrochemical doping.
