Dithieno[2,3-b;3′,2′-d]thiophenes (DTT), having substituted phenyl groups at 3- and 4-carbons, have been synthesized, applying 2,5-diketone ring closure reaction using P4S10. Cyclic voltammetry studies indicated that all the DTTs had the oxidation potentials between 1.19 and 1.70 V. Computational calculations displayed positive radical spin densities at C2 positions for DTTs and negative for their
已经合成了二噻吩并 [2,3-b;3',2'-d] 噻吩 (DTT),在 3-和 4-碳上具有取代的苯基,使用 P4S10 应用 2,5-二酮闭环反应。循环伏安法研究表明,所有 DTT 的氧化电位都在 1.19 和 1.70 V 之间。计算计算显示 DTT 在 C2 位置的自由基自旋密度为正,而二聚体为负。图形概要
