Selenium analogues of TMET-TTP (2-(4,5-bisthiomethyl-1,3-dithiol-2-ylidene)-5-(4,5-ethylenedithio-1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene) 1b-d have been synthesized. The iodine salt (1b)4I3 exhibits moderately high conductivity (σrt=13S cm−1) with semiconducting temperature dependence, and the donor arrangement is θ-type. The present θ-type salt as well as TMET-TTP salts is located at the insulating limit in the universal phase diagram of θ-phases.
TMET-TTP(2-(4,5-双硫甲基-1,3-二硫杂环-2-亚基)-5-(4,5-乙烯基二硫-1,3-二硫杂环-2-亚基)-1,3,4,6-四硫杂五环烯)的硒类似物1b-d已被合成。碘盐(1b)4I3表现出中等高度的导电性(σrt=13S cm−1),具有半导体温度依赖性,且给体排列为θ型。目前的θ型盐以及TMET-TTP盐位于θ相的普遍相图中的绝缘极限处。
