Two new organic electron donor molecules are synthesized on the basis of the ethylthio-substituted tetrathiapentalenes with a methylenedithio or a 1,3-dithiane unit. These donors provide four isostructural radical-cation salts, which belong to a new crystal type with uniform stacks of the donor molecules. These salts show metallic conductivity down to low temperatures, linear temperature dependence of the thermoelectric power, and asymmetrical ESR lineshapes. The obtained uniform structure is compared with the previous uniform structure from the viewpoint of crystal packing.
在乙硫基取代的四硫戊二烯的基础上,合成了两种新的有机电子供体分子,其中包含一个亚甲基二硫或1,3-二噻烷单元。这些供体分子提供了四种同构的自由基阳离子盐,它们属于一种新的晶体类型,具有均匀堆叠的供体分子。这些盐在低温下表现出金属导电性,热电功率与温度呈线性关系,并且具有不对称的ESR线形。从晶体堆积的角度将获得的均匀结构与之前的均匀结构进行了比较。
