2-Cyanoethylthio-1,3-Dithiole-2-Selone—New Precusors in Tetrathiafulvalene Synthesis. Tetrathiafulvalenes, Incorporating 1,3,4-Oxadiazole and Cyanoethyl Moieties
In recent years the interest of molecular electronics in organic compounds able to produce electroactive organic thin films by Langmuir-Blodgett (LB) technique has considerably increased. Various amphiphilic tetrathiafulvalenes with long alkyl chains are considered to be very promising from this point of view . But recent studies on LB films based on non-amphiphilic TTF derivatives [2, 3, 4] have demonstrated that the attachment of long-chain substituents is not a prerequisite for creating of conducting LB films of TTF-based CT complexes; it is interesting that some of them include thiobenzyl-moieties [e.g., 2]. In 1998 a new asymmetrically substituted TTF derivative, namely dibenzylthiodimethylthioTTF, was reported to form a stable monolayer in a mixture with arachidic acid . For the same purposes we have synthesised a new group of TTFs with benzylthio substituents, fluorinated in various positions of a benzene ring, and investigated their π-donor ability .
