A novel selenium-containing bis-fused tetrathiafulvalene donor, TSM-TTP (2,5-bis[4,5-bis(methylseleno)-1,3-dithiol-2-ylidene]-1,3,4,6-tetrathiapentalene) forms a 3 : 5 triiodide salt, (TSM-TTP)(I3)5/3. This salt has uniform one-dimensional columns of the donors, and is isostructural to the corresponding complex of the sulfur analog. This compound shows a high electrical conductivity, 200 S cm−1 at room temperature, and undergoes a metal-insulator transition around 20 K. Another insulating (σrt = 0.03 S cm−1) phase with trimerized columns is also obtained.
一种新型含硒双融合四硫杂戊烯供体 TSM-TTP(2,5-双[4,5-双(甲基硒)-1,3-二硫醇-2-亚基]-1,3,4,6-四硫杂戊烯)形成了 3 : 5 三碘盐 (TSM-TTP)(I3)5/3。这种盐具有均匀的一维供体柱,与硫类似物的相应复合物结构相同。这种化合物具有很高的导电性,室温下为 200 S cm-1,并在 20 K 左右发生金属-绝缘体转变。
