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

Abstract The new π -electron donor bis(1.3-cylobutylenedithio)tetrathiafulvalene (1.3-CBDT-TTF), which is only slightly different in the periphery of the molecule with respect to the well-known donor BEDT-TTF, was synthesized. The molecular 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 [AuI 2 ], (1.3-CBDT-TTF) x (ReO 4 ) y and (1.3-CBDT-TTF) 2 PF 6 ·THF were characterized by X-ray analyses. The room temperature electrical resistivities of the radical salts are low and range between 0.5 and 5 Ω cm.
