Semiconducting Langmuir–Blodgett films of non-amphiphilic ethylenedithio–tetrathiafulvalene derivatives bearing pyridine and pyridinium substituents
Abstract
Compounds 1 and 2 form stable Langmuir–Blodgett films which after iodine doping are semiconducting (σrt= 10–3 S cm–1), demonstrating that the attachment of long alkyl chains is not a prerequisite for the formation of conducting LB films of tetrathiafulvalene (TTF)-based charge-transfer complexes.
