Conducting radical salts of the new electron donor bis(1.3-cyclobutylenedithio)tetrathiafulvalene

The new pi -electron donor bis(1.3-cylobutylenedithio)tetrathiafulvalene (1 .3-CBDT-TTF), which is only slightly different in the periphery of the mole cule with respect to the well-known donor BEDT-TTF was synthesized. The mol ecular structure has been characterized and the electrochemical behavior of this new donor was investigated. New cation radical salts were prepared by electrocrystallization methods. The structures of (1.3-CBDT-TTF)I-2, (1.3- CBDT-TtF)(2)[AuI2], (1.3-CBDT-TTF)(x)(ReO4)(y) and (1.3-CBDT-TTF)(2)PF6.THF were characterized by X-ray analyses. The room temperature electrical resi stivities of the radical salts are low and range between 0.5 and 5 Omega cm . (C) 2001 Elsevier Science B.V, All rights reserved.
