摘要：

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.
