Novel electron acceptors bearing a heteroquinonoid system, 5,5′-bis(dicyanomethylene)-5,5′-dihydro-Δ2,2′-bithiophene, its 3,3′-dichloro, 3,3′-dibromo, and 3,3′,4,4′-tetrabromo derivatives, and 5,5″-bis(dicyanomethylene)5,5″-dihydro-Δ2,2′:5′,2″-terthiophene were synthesized by the action of tetracyanoethylene oxide or by Pd(0)-catalyzed substitution reactions with sodium dicyanomethanide on the corresponding
带有杂醌系统的新型电子受体,5,5'-双(二氰基亚甲基)-5,5'-二氢-Δ2,2'-联噻吩,其 3,3'-二氯、3,3'-二溴和 3, 3',4,4'-四溴衍生物和5,5"-双(二氰基亚甲基)5,5"-二氢-Δ2,2':5',2"-三噻吩通过四氰基环氧乙烷的作用或通过Pd(0)-催化的二氰基甲烷化钠在相应的 α,α'-二卤杂芳烃上的取代反应。正如预期的那样,它们显示出非常小的现场库仑排斥力,并提供了几种具有电子供体(如六亚甲基四碲富瓦烯)的高导电分子复合物。
