3′-dichloro-5,5′-bis(dicyanomethylene)-Δ2.2′-bi(3-thiolene) (DCBT), and 3,3′-dibromo-5,5′-bis(dicyanomethylene)-Δ2.2′-bi(3-selenolene) (DBBS). Although the resulting complexes are mostly 1:1 stoichiometrical, the TCNQ complexes tend to favor a composition rich in acceptors; on the contrary, the DMTCNQ and DMOTCNQ complexes tend to favor a composition rich in donors. Their electrical conductivities range widely
一系列蒽[1,9-cd : 4,10-c'd']双[1,2]二硫醇、二硒醇和二碲烯的二甲基和四甲基衍生物已被制备为新型电子供体。引入的甲基不仅可以提高供体强度,还可以提高溶解度,使其能够与各种电子受体如 7,7,8,8-四氰基醌二甲烷 (TCNQ)、其 2, 3,5,6-四氟衍生物, 2,5-二甲基衍生物 (DMTCNQ), 2,5-二甲氧基衍生物 (DMOTCNQ), 2,6-双(二氰基亚甲基)-2,6-二氢萘 (TNAP), 3,3 '-dichloro-5,5'-bis(dicyanomethylene)-Δ2.2'-bi(3-thiolene) (DCBT), and 3,3'-dibromo-5,5'-bis(dicyanomethylene)-Δ2.2 '-双(3-硒烯)(DBBS)。虽然由此产生的配合物大多是 1:1 的化学计量比,TCNQ 复合物倾向于支持富含受体的组合物;相反,DMTCNQ
