Conducting langmuir-blodgett films of new amphiphilic tetrathiafulvalene derivatives

Abstract New mono-functionalised, amphiphilic tetrathiafulvalene (TTF) derivatives have been synthesised and shown to form Langmuir-Blodgettt films, some of which are semiconducting ( δ rt = 10 −5 -10 −2 Scm −1 after iodine doping. These layers have been characterised by UV-Visible and IR spectroscopy in the undoped and doped states. X-ray crystal structures of related TTF derivatives substituted with a thioester and a thioamide group are presented.
