Electrically Conducting Organic Materials: Design, Synthesis and Characterization
Abstract
Our activities during the last six months continue to be in five main research areas: Synthesis of D2A type molecules; Synthesis of rigid A2D type molecules; Electrochemical measurements and salt formation; Synthesis of telluro derivatives of TTF. We prepared the two quinones 1 and 2 and converted them to the corresponding dicyanimines 3 and 4. We are currently preparing the dicyanimine derivatives of 5 and 6 and learning about the solid state packing properties of all the compounds 1-6. We are pursuing A2D templates with sulfur atoms linking the moieties. Some of those compounds exhibit a zig-zag type of stacking with considerable more overlap than usual. In the search for new organic conductors, it is convenient to match donors and acceptors by their electrochemistry. Cyclic voltametric data on some of the D2A molecules are shown. All experiments were carried out under argon in THF containing tetrabutylammonium tetrafluoroborate as electrolyte using platinum electrode as the working electrode and silver/silver chloride as the reference. We are measuring the electrochemical potential of all the other compounds described in this report. We were able to synthesize two new compounds which are at the same time Te - TTF derivatives and TTF - dimers. Keywords: Crystals, Electrical conductivity.
