| 我々は新規なピラジン環縮合TSeF誘導体PTSeF(4,5-pyrazinotetraselenafulvalene)を合成し、その構造解析およびCyclic Voltammetryの測定を行った。カチオンラジカル塩はClO4-塩(1:1塩)とPF6-塩が得られ、その電気抵抗の温度依存性は半導体的であった。今後、他の対アニオンとの結晶作成を試みる予定である。 |
| We synthesized a novel donor containing pyrazino-ring: PTSeF. The donor shows two pairs of reversible redox waves (+0 79 and 1 14 V vs. Ag/AgCl in PhCN). The crystal structure was determined. The cation radical salts were prepared by electrolytic oxidation. The ClO4- and PF6- salts are semiconductors, due to a 1:1 stoichiometry in respect of the ClO4- salt. |
