The title compounds (2) were synthesized as the donor components for organic conductors, and preparation and electrical properties of their cation radical salts were investigated. Among various cation radical salts obtained so far, AsF6 salt of ethylenedithio-2 and SbF6 salt of ethylenedioxy-2 showed metallic temperature dependence of conductivities down to 0.6 K.
                                    我们合成了标题化合物 (2) 作为有机导体的供体成分,并研究了其阳离子自由基盐的制备和电学特性。在目前获得的各种阳离子自由基盐中,亚乙二
硫基-2 的 AsF6 盐和亚乙二氧基-2 的 SbF6 盐的电导率在 0.6 K 以下显示出
金属温度依赖性。
