In order to examine Little’s model for organic superconductors, several azulene-substituted TTF derivatives were synthesized. Measurements of the oxidation potentials using cyclic voltammetry (CV) provide their donor abilities. The molecular structure of AET (azulenoethylenedithiotetrathiafulvalene) was determined by X-ray analysis. Cation radical salts of synthesized donors with BF4– , ClO4– , PF6– , AsF6– and [Pt(dmit)2 ]n–(dmit=C3S52–=2-thioxo-1,3-dithiole-4,5-dithiolate) were prepared by galvanostatic electrolyses. Temperature-dependent electrical resistances indicate that these salts are all semiconductive. The crystal structure of (AET)2 [Pt(dmit)2 ] was determined by X-ray analysis and its electronic structure is discussed.
